When I search on the Mentor support website, the answer is always:
Your search - ... - did not match any results
This is totally different from the results in the past. Then I was always flooded with results, and the problem was to find the usable answers for my question.
For some of my products there is a message that the support is expired, but e.g. for Xpedition Enterprise there is no such message, so I assume that support should be active.
