it looks like you have a corrupted version..via add/remove programs, uninstall LW...then redownload it, this time from www.limewire.com

Either that or you have a virus. I think that sometimes pops up when you have a virus. I'm not completely sure.

i have downloaded it from the offical site and ive checked i havnt got a virus

hmmmm...well you posted:

file [LimeWire.jar] has hash of [212CE41FC54827F4534B27063325B6BB] instead of expected [0B27FDA0142B4B9559F936A9C3EBBDB8]

there is a hash inconsistency..which indicates something is wacked...follow my suggestion and see if that works....

I don't know if this will help but try to install limewire. And uninstall java if it's on your computer and reinstall it. It's worth a try.
