*adds to solutions notes*So your launcher was trying to upload a crash dump? Did you crash when the servers went down?Also check for the following files in your MxO install directory and delete them.:any files ending in .dmp ( eg: MatrixOnline_7.5591_crash_0.dmp )a matching text file ( eg: MatrixOnline_7.5591_crash_0.dmp.txt )a crash log ( eg: ClientErrors_0.txt )the crash reporter log file ( eg: crashreporter.log )You should be able to turn the crash reporter back on safely then.
