That's very strange, what you have described bellow does sound like corrupted files. I recommend following the steps bellow :

1. Redownload the game

2. Place the archive in a drive with enough space (at least 4 gb free)

3. Use 7zip to unzip , selecting unzip here (so that it doesn't cache them in C: drive)

If there are still errors you could try disabling any antivirus software (although this was never needed before, and the archive was not modified for more then a year).

The gameplay should look like in Gameplay vids (can be seen above in main post), if it looks different then there has to be some errors.

I hope this helps,

Cheers
