Concurrent users not working...

We purchased a two user license and can only have one user in the database at a time. Does anyone else have this issue or do you have a resolution?

Good morning Bob. If your registered name on Elsmar matches what we have on file I believe I am your account manager. I had our support team double check to make sure that your license was set up correctly and that has been verified. For additional troubleshooting, please contact our support team. Thank you.
