Some users have found a bug with the following features:
1) CFDEMworkbench has not been used for at least 2 days.
2) CFDEMworkbench starts correctly a first time.
3) Close CFDEMworkbench.
4) Reopen it and the error appears.
Root cause: the license server was not able to synchronize itself with the local PC.
Temporary solution: if you reopen CFDEMworkbench after 5 hours then it runs correctly.
Releases affected: all the STARTER/PRO with release number <= v2.1.4.
Releases NOT affected: In-House server.
We are working to fix the bug. In few days we are going to deliver a new release.
Thanks for your patience.
