Idk, my pc's just apparently doesn't want to work with rar. Since I didn't experience any problems with this on my old Win Pc, but after buying a new one, my rar files just refuse to work and making Error... (mb cuz my old Win Pc was my mom's pc and she just smarter, than me?) It's the same on my Mac , but it's mb cuz he a little old... Sorry for this extra work for you :_)
