hi,
i just opened up rig manager (i hadn't used it for a while) and it didn't recognize my Profiler and had an error.
it said that i need to upgrade to the newest version of rig manager, so i installed the latest version for windows 7 64bit.
then i restartet my profiler but the same error happened AND my profiler didn't react anymore. so i turned it of and wanted to restart it,
but since then the profiler didn't start up anymore!
i don't know what i shall do....
