WebShop

Did anybody worked with this situation before. Running the new Navision Attain license file with Navision Financial 2.60. We are planning to upgrade but not ready yet and our license is expiring. When I put in the new Attain license, WebShop is not able to function anymore as it complain the permission error. Does anybody have any solution to work around this? Thank you very much for your help in advance. Steven.
