I am on a trial license. When I try to SetLicense, I get the error "No connection could be made because the target machine actively refused it. (localhost:55518)" . Not sure how to deal with this. Any help is appreciated.

You're right, the url was pointing to local host by accident (for local testing). I've just uploaded a fixed version (CadLib 5.0 that is). Thank you for the report! - Wout

Hi, Looks like the new version of CadLib 5.0.39.25 has some incompatibilities. Please refer the attached snippet.

Can you check the dll version numbers? You can check that in Windows explorer, right click the dll, and then look in the details tab. The version should be .25 on all dll's. - Wout

Unfortunately it is not. Only this WW.dll has the previous version.

Something was wrong with the setup somehow indeed, I don't understand how yet, but I've just uploaded a new version (.26). - Wout
