Sims 3 Error? Perhaps Hard Drive?

I got a portable hard drive, and installed the sims + expansion packs. My dad wiped the hard drive thinking it was his own, and now that i've re installed the sims, it won't let me open the launcher, or TS3 delphy helper monkey. It just says I should tell microsoft about this error. BLA. I've had this before with just the launcher but I forget how it's fixed? Please help. .. Ps I do know you can byass the launcher, but I don't want to as it's to install CC.
