Description: Unable to activate as there are no possible activation methods

Solution: examine the .cm.ini file. There are three possible activation methods for a token:
Trial
Product Key
Network client

All of these can be forbidden in the .cm.ini file (see the manual for details), forbidding them all will cause a 910 error. Network client activation is implicitly forbidden with network server type installations (cmnet or cmserver), at least one of either Trial or Product Key must be allowed.
