Red box and exclamation mark popping up while inserting detectors objects


Hi!

I am getting a very strange error while trying to insert detector rectangles while using Zemax in Non Sequential Mode. 

I am working with CAD objects, but as soon as I try to insert simple detectors, the raw gets highlighted with a strange red box:

This can happen also with the other objects from time to time:

Zemax stops working and I have to force quitting the software. When I reopen Zemax I get these two errors:

Does anybody know why this happens?

I thought it was because of the big cad files, so I tried to insert only simple detectors: 

Unfurtunately I get the same behavior and I have to quit Zemax.

I thank you in advance for your help!

Cheersm

Giulia.

Hello! 

I suspect it’s a bad catalog or other file in Opticstudio’s DATA folders.  To refresh it, delete VERSION.LOG from Documents\zemax\license, and restart opticstudio. It will recopy all the default files for you.

Hi Don!

Thank you for your reply.

I actually reinstalled Zemax another time and I renamed the Zemax folder differently. By doing this the reinstallation worked finally and the software works again.

Thank you for your suggestion!

Cheers,

Giulia.
