I have an IAM that made using 5.3 and have now loaded 6. I try and open the assembly, and get the standard message about updating the assembly because things have changed that could affect position etc...I click OK then it opens. The problem is when I try to save it after opening it. When I try and I get the messages about migrating old versions, and do I want to continue. And then it crashes and generates an error log. Any suggestions?? Thanks.
