I have emailed Brad to see if there is any way I can access the WCP database so that the data can be exported. I have previously managed to import most of the details from a worklist exported to a PDF file, but this isn't an option if you can't access your copy WCP due to licensing issues, etc.
If they are no longer developing/supporting WCP, I would hope that they would want to help me provide a migration path for you to another system. I would obviously import the data into Aworka, but you would then be free to export it for another system if you wanted to.
Fingers crossed for a positive response from Brad...
