cadence ams problem with fatal error

[sixth]

Dear all

I met a fatal error duing runing cadence AMS simulator. The version of ncsim i used is IUS8.1 and the spectre version is MMSIM7.1.
In the end of log file, it appears the following error information
"you have no permission to run spectre circuit simulator".
It is not a licence probelm because i can still run other normal analog simulation with spectre.
what's wrong with my simulator? Thanks a lot if you can give me a hand.

You may have a license to run only some types of simulations (just guessing).

Try to check your license server log (if you have access to the log) and see if there is something there about some missing feature.

Thanks for your reply.
but it is not a license problem. i have checked the license log file and all the features are checked out.
