I wouldn't say it opened "THE" file, it opened "A" file. This is what it did before. Here is a pic of HyperShot and KeyShot side by side. The file it should have opened should have been 4 levers.
Doesn't matter what file I open, it makes a mess of it and literally takes minutes to open.
I want to note: Claus Jensen has suggested about everything he can, same issue. I finally said screw it and loaded a new version of Vista. The other version was a Home Edition so this is actually a different version, Vista Ultimate.
If it make any difference, I purchased this December 31'st. I have read that you are not supporting anything purchased in December??
