License Problems

[Bruce Hart]

Today all of a sudden I am having license issues where I can render one minute and the next I get the "Could not obtain license (1002)" error - during the same Max session. At times the license comes back. I have a dongle plugged into my local machine, which I thought would rule out network connection problems with my office server.

At first I thought perhaps the dongle is becoming faulty, but a colleage is having the same license problems today. (He also has a dongle on his own workstation).

The Wibu Server is running and the VRLservice is running. The dongle report says there is a license present. My only thoughts are that we run AVG Virus scanner in our office and it's just done an update. Somehow it might be interfering with the Vray license? Going into the AVG settings I see it has made an exception to the VRLservise, so I'm not sure what's going on.

Any ideas? Has anyone had problems with AVG Anti-Virus (Business Edition)?

Edit:
Just had another scene stop working. I can "fix" it by manually stopping the VRLservice and the startvrlservice starts it again. After that Vray can render again with a license. Still not sure why it is doing this all of a sudden.????

OK - I think I've found it. The VRLservice was in the exceptions list of the AVG scanner but the Wibu network server was not. Adding that exception seems to have fixed it. If that helps anyone with the same issue - all good

Damn - I spoke too soon. Still happening. However I think it has something to do with AVG Virus scanner....
At the moment I can sometimes not see the Indirect Illumination panel options in the Renderer (it's blank), but the image can still render. At other times I can render once, the license can't be found on the second render, and then myseriously come back on the third. Weird. I can still bring Vray back by manually stopping VRLservice and letting it restart.
