you should using mendix version selector to launch mendix modeler desktop program.
Keep on sign-in and sign-out at least 10 times. One sign-in action would be in favor of you. I tried the same with Modeler 7.10.0 and 7.13.1 and I succeeded.
Hi Hamid,
I believe Mohan has answered your question in his own post.
