Updated to 6.x-2.0-beta and many issues

I updated to Version 2.0-beta2 and I ran into a few issues...

1: WinRAR said it's a "Corrupt Archive".
2: I had to reinstall Version 1.0-beta2 because 2.0 didn't have Views Slideshow in it (probably the corrupt part)
3: No slideshow user controls showing up (again, probably part of the corrupt issue)
