TS search failed in Dmol3

Dear MS users,

When I ran the TS search in Dmol3, it failed with the following:

Message: DMol3 job failed
Error: DMol3 exiting
Checked out license feature: MS_dmol_site [for msi

I tried to decrease the run of parallel cores from 46 to 30, but it still failed!

How can I deal with this problem?

Many thanks.
