Reset Warnings in iTunes Windows

[dotdotdot]

SO in iTunes 5 i accidently clicked "Do Not Warn me Again" when I deleted a song and now if i accidently delete a song its gone from my library but i dont know what i deleted!

So, how can I reset that warning?

Actually having this same problem. Got another warning on the PC saying a certain file couldn't be added b/c it couldn't be found, and I clicked "Don't warn me again." Then I saw there were 15 more errors, which I couldn't check...

HOw do I re-enable warnings so that I can see what the errors were again?

Thanks in advance.
