Did you try e-mailing the author? Since the files where the errors are being generated are encrypted, he is the person you need to fix this. His contact info is available in the Extension Warehouse. He’s more likely to see an e-mail from you than stumble on your thread in this forum which he may or may not visit.

thanks, I was hoping someone else encountered this problem and already had a solution
