Heh! I had a similar problem recently... Was "experimenting" installing old software from some good old Amiga Format CDs on to my A3K/OS3.9, and some of the installation routines there kindly splattered some of the Reaction classes with older ClassAct ones! Took me a while to sort out the mess!
I think next time, I'll do a "test run" in WinUAE rather than potentially cripple my real A3K!
