ive had limewire for a while and recently it started to crash. i upgraded to the newest version and i keep getting the same messages the loading screen comes on and i get a error saying:
Your save folder is not valid. it may have been disabled you may not have permission to write it, or there may be another problem. please choose a different folder.
Then i click ok and i get a fatal error sayin a fatal internal error has been found and will now exit ect. and i click review and I get this:
