Like many here, I run Red Hat Linux 7.2, soon to be 7.3. Well, RH has a program installed called kaffe. What this is supposed to do is rearrange the byte order (or something like that) for java. Well, limewire doesn't like this very much and will thus give you a "Error: Unrecognized JVM specific option -Xx.....something something..." Well, like nDiScReEt said. Uninstall the kaffee program and set the java_home environment variable and add it to your path and you'll have limewire with no problems! So, in respect, thanks must go to nDiScReEt, all I've done is repeated what this person said.

have fun
