sounds like your rr.ini got corrupted somehow. 2.2 uses rr.ini to store all its settings so it reads and writes to this file multiple times per session. Its possible that during your last shutdown something bad happened and RR didnt quite exit correctly and the file got messed up.
Personally ive never seen this happen.
3.0 does not use rr.ini for any of the skins settings, everything is stored in skin.ini inside the skins folder. So the update should smooth that over by never writing to rr.ini
if this is something that happens more than this one time, let me know as it shouldn't (and for me it hasnt) ever ever happen.
