Beyond belief! 

Two months of non-use, I casually click my trusted Poser 13 link and?

And it always ran fine, so what is going on here????

Tried re-installing and the same issue. Checked all my anti-virus settings and it is all fine. I paid a lot of money for Poser 13 and 12.

Is that it now?

Have both installed and neither boots up anymore. Absolutely furious and scared I will lose my settings, library structure and everything. 

If anyone has any tip that doesn't utterly destroy everything, I would be indebted. 

Cheers
