no, not really talking about that. if i did that, then all of my Windows programs would be gone too. just talking about resetting wine to defaults or something because there seems to be a problem with my installation since this bug isn't reproducible anywhere else.
Well you can't really 'reset' wine without losing/breaking apps, since most will change the wineprefix in some way.
