Dear community,

i am facing problems with the 2021 version of MS. (The 2020 version runs flawless.)
I tried to perform a test calculation with CASTEP and got the following output:

Licensing Error !
Error: Manual heartbeat setup for MS_castep license failed
Failed to check out licenses
Trace stack not available

I checked the status of the license server (lpver & lp_tester)

License Pack Version: 21.1.100

Checking License Pack version on server...

Server License Pack Version: Unavailable

AND

Attempting checkout...

Error: #-83 (LP 21.1.100)
Version of vendor daemon is too old.
Feature: License_Holder
License path: /<...>/BIOVIA/BIOVIA_LicensePack/Licenses/msi.lic:1715@:/<...>/BIOVIA/BIOVIA_LicensePack/share/data/*.lic:
FlexNet Licensing error:-83,147

Do you have any ideas what is going on with the license pack and the vendor deamon?
Any help is appreciated!
