--- Comment #5 from Fabian Maurer dark.shadow4@web.de --- If you downgraded it from the repos of your distro, it's fine, I guess. Are all the programs that aren't working anymore in the same wineprefix?
And what is the output if you run wine to try and open one of these programs from the commandline?
