Music Wont Play! :\

[jessuba]

I was hoping someone on here would be able to help me with my problem, Im not the most computer savy person:
Today I got the motherboard on my computer replaced (computer was acting funky so Im no longer using limewire)...anyways. Its replaced now but when I turned on Realplayer to listen to music this is what happened: Anything that was from a cd would play. Anything that was downloaded from Limewire does this: I click on song. Realplayer brings up a message that says Autoupdate- Realplayer needs to download new software to play this clip. I click okay. Then it tries to update it (it brings up that popup with the red flashy bar at the bottom something about "wait while it downloads") and it tries so fast that I cant see it. Then it goes to another popup that says "Autoupdate-There is no software update available from Real to support this content." They are mostly mp3 files. Thank you all so much! I really appreciate it. -Jess
