Papanui Cycles review for Stocky

I enter a invoice and go to print labels, I get this error message. Had stocky now for a number of years, this has just happened. error message printing label extensions , the calling thread cannot access this object because of a different thread owns it , bad request. 1. Have reloaded Dymo and the drivers ( shopify tech support helped and was excellent ) 2. Have called dymo global and all is working from their end and printing correctly. 3. It has to be a stocky issue? Any help from stocky Tech department. Thanks Kevin Lee Papanui Cycles Ltd NZ
