After updating the floating license, EM simulations may generate an error message like the following (on one line):
...License Policy Error: There are not enough instances of XXX_100 available to run the job as requested.
Try reducing the minimum number of processors for the job and submit it again:...
If you are certain that licenses or tokens are available, but still see this message, then you are probably using a version of the AWR Design Environment that is older than 11.05. Please update to the latest available version, or at least to version 11.05, to successfully use your license for performing EM simulations.
