i had v4.2.3 working perfectly for a couple of weeks, then my 7 yo did "something" to my laptop (Dell 510m with Xp-2) - end result was a restore and i needed to reinstall almost all apps. Everything else resinstalled fine, except for LimeWire - I used the control panel, etc to try and reinstall - no luck - then removed everything and reinstalled - no luck. have now downloaded and installed v4.2.6 and everthing installs fine, but nothing happens when I start the program - nothing comes up in the task manager either - any ideas?
