You’re listening to your iPod and suddenly you notice that the album artwork is different for the song you’re listening to. You’re like “What the heck?” so you go to see if this has affected any other songs and to your dismay, it has 
Don’t worry, there’s a good chance you could fix this. First, in iTunes, click on your iPod. Now click the Music tab and uncheck Display album artwork on your ipod. Do this and at the top where it usually has the information of the currently playing song, it will say Deleting artwork from your iPod, don’t freak out this doesn’t mean you’ll have to get it all over again. Once it’s completely done, CHECK Display album artwork on your ipod over again and it will then say Optimizing artwork for your iPod at the top. Once it’s done, disconnect your iPod and you should have your artwork back! 
If you use Daemon Tools chances are you also use the awxDTools which adds a nice little context menu whenever you right click on an image file so that you can easily mount disk images.
Well one problem that sometimes happens to me is that it mysteriously disappears. After some searching, I realized that it was a combination of PowerISO and MagicISO that were causing the problem. In MagiISO, I went to View > Settings. Then in the File Associations tab I clicked Clear All. This brought the icon back, but this isn’t absolutely necessary so if it didn’t do it for you don’t panic.
Next in PowerISO I went to Options > Configuration and unchecked Enable Shell Integration.
Now go to Start > All Programs > arniWORX > awxDTools > Re-Register Extension. This is like a ‘refresh’ of the extension on the system. Next, you might have to restart (Or you can terminate explorer.exe and start it over again but just restart if you’re confused). You should now see the menu again! If you’re wondering why I use both PowerISO and MagicISO it’s because stupid kids on the Internetz think it’s cool to upload all types of image files. PowerISO is the only one that supports DAA and MagiISO is the only one that supports UIF. Other than that, Daemon Tools supports any other one like Alochol’s MDF etc.
One day you just click on the Live Messenger Icon and it won’t start up, what the heck? You check the task manager and you see it’s still running, in fact if you click on it various times it runs as many instances. What the heck is going on here? You think it might be a virus. You re-install, scan your computer for viruses/spyware, nothing.
After a while of searching, I found it has to do with your router. Live Messenger fails to load due to firewall exception errors with your router. Most people who had this problem had D-Link routers. Some solved it by simply reseting their router, but for some that didn’t work. Instead they discovered that they also had to turn off UPnP Settings. Turning this off consequently resets the router as well. Once it’s back up, you’ll be glad to know that Live Messenger now works fine.

If you ever come by the problem where all of a sudden your music’s artwork wont show, it’s most likely due to an upgrade in iTunes. Basically you now have to check a box that says Display album artwork on your iPod in the Music tab when your iPod is select on the left list on iTunes. After this click apply on the bottom right, and you’ll notice that your iPod is now doing something like Optimizing the artwork for the iPod, this might take a while depending on your computer and the amount of songs you have. After this though, I ejected and was glad to see my artwork being shown
