Unarchiver 3.6.1 unable to extract rar files

I've been trying this for two weeks now after getting notice of an update to The Unarchiver which comes with Mac OS X. I am running OS X10. 8.2 which is current. The update installs without error but when I try to extract several .rar files, I get an error to the effect that it can't extract to a folder. I've tried this about 8 times, same experience. When it fails, I restore Unarchiver 3.5.1 from backup and extract rar files with it and it works fine. 3.6.1 says it is fixing an folder extract error when in fact it causes one where there was none in the first place. I would just as soon as forget about 3.6.1 but I don't know how to permanently get rid of it. When I restore from backup to 3.5.1, then it puts 3.6.1 back in the update que. Does anyone know how to fix the problem I'm having with 3.6.1 and if not, how do I get rid of it coming back to the update que? Thanks.
