Hi Graham,
Please check the following:
1. Check whether the project still references nevron dlls. If so simply remove them.
2. Check whether the licenses.licx file contains entries for this type.
You can also post the output file for review - the compiler should specify the source file that references this type.
We hope this helps- let us know if you meet any problems or have any questions.
Best Regards,
Nevron Support Team
