PickMaster PowerPac

Dear Experts,
When I try to open my project in PickMaster PowerPac ( created few days ago), I get message: "The controller with the same name is used" and all options are locked/disabled. How can I solve this?
I have premium licenses for both (RS and PickMaster PowerPac)
Thank you in advanced, best regards,
Matjaž
