Hi, everyone

I am using the EMPro 2011.02, the latest version. Recently, I encounted the following license error.

After I started the simulation (which is the only simulation) , one window poped up and show the following message:
Launch of multiple simulation jobs/simulations error
basic EMDS simulation features
You are attempting to launch another job/simulation in addition to the one that is already running.
When there are additional licenses available, you must set an environment variable to enable the check out of additional licenses when launching multiple simultaneou jobs/simulations of the same type.
To enable this capability exit the program and set the following environment variable:

I am quite puzzled about this error.
1) I only started one simulation, why the multiple error occurred?
2) I followed the instructions to change the environment variable, however, it doesn't work.

With my best wishes,
