I cant seem to update mine, it keeps telling me that "program execute failed" when i launch the game launcher. The rumble fighter client doesnt download and it just downloads a 1 kb file.
Make sure your firewall or anti-virus is not blocking it. Make sure the rumble fighter folder is not set to "read-only". Try doing a windows restore to a time before the problem started to happen.
Thats messed up, i had to ask someone to share their rumblefighter.exe and rumblelauncher.exe before it worked...thats really screwed up.
