I'm afraid you're still the very, very standfast victim of a misinformation.

Unless we have another "German HQ" that I do not know of, your hope for another 6.4 version is in vain. 6.40 Team Commercial works flawlessly so far. No other team has reported any problem. As I've told you last week, the erroneous support notice was pulled.

If you still want our help in this regard, please post in the "Ask Conitec" forum or contact the support, and submit the 3 requested logs. They can be generated in a matter of minutes. I'm confident that we'll then soon find the reason of your and your team's problem.
