Limewire tries to crash my pc, so does frostwire.

[diddyman4real]

I have limewire pro, and when i first installed it, it worked perfectly. then about 1 day ago, i tried to run it, the logo came up and normally the bar would say loadinmg engine, yada yada yada, but now it won't say anything! it just sits there withthe logo, the bar doesn't run anything at all and it just overloads the memory until it just causes a crash to my pc, and frostwire is doing the same thing. my pc uses vista. whats wrong with it, is it my java? or is it vista related? my java is version 6 upate three. my limewire is 4.14.3. please help me.
