Draftsight activation problem-program crash! Please help.

Hello,

I have a problem with Draftsight. After user fills in the activation form, the following message is displayed:

 

I tryed removing/renaming the data from regedit and re-activating the product. No help.

The problem persists. Machine is on Windows 8.

Have no problems on other machines and OSs.

 

The thing I tryed is to switch to another user.

If I switch to any other user on the same machine, I can go trough process of activation and use the product itself. Do you have any clue what is the problem and how to reslove this?

 

Thank you in advance.
