Apologies if this situation has been covered before.

Installed Poser 7 about 10 days ago.
All was running fine, worked up several images,  till it apparently garbaged a .pz3 file.
Trying to open the file resulted in a windows error message that poser had caused a Windows fault and would close. After that the program would not even load without causing a crash.

Since then I have uninstalled and re-unstalled Poser7 4 times.
Even searched the windows registry and removed all reference to poser7 that I could find.
Tried installing in different directories and on different hard disk (same computer though).
Each time now it crashes on start-up, the program won't even load.

I still have Poser6 installed and it runs fine.
I also have Carrara, Hex, DAZStudio, Photoshop CS and several others and no problems.
Running diagnostics on my systems turns up no errors.
I have made no changes to my system or installed any additional programs since installing and running Poser7 10 days ago, all other programs run without problems.

I doubt the the installer files are corrupt as the program was originally installed from the same files and was running great prior to the (aparently) corrupted file issue.

I'm a IT guy and this one has me totally stumped.

Any advice appreciated.
