PR 0.86 and mumble won't start??

[rough77]

i've been playin' 0.86 always with NO problem.
i returned from my holidays, turned my PC on - and ONLY PR 0.86 (the 0.856) version + mumble won't start!

it says: bla bla program could not be started because of a programfailure - you should reinstall the program (translation from german: "diese anwendung konnte nicht gestartet werden, da die anwendungskonfig. nicht ordnungsgeäß ist. zur problembehebung sollten sie die anwendung neu installieren". ).

now that's really strange - isn't it?

for sure i've reinstalled PR completely - did not solve the problem.

BF2 vanilla: starts
PR 0.856: starts
all other programs: start
