Having trouble uninstalling an old copy of RoR

[SybilSixx66]

Alright, si I'm gonna try uninstaling and reinstalling RoR. I might already have the right version, but I thought I'd try it. Now, when I get the installer up, it asks if I want to uninstall or update the game. If I try uninstall, the dialog box asking if I really want to uninstall the game comes up and about a second after that, crashes the program. If I try update, I get an error message saying the program could not connect to the steam server and then crashes. If I try to run the copy I already have, it tells me that there's files missing, mainly .dll files.

I believe you can just delete your program files folder and change then name of your documents rigs of rods folder(if you have anything you dont want to lose) and re install.
