Flexlm 9.5 crashes when used with quartus 9.1

Hi everybody,

we have a big problem. Since we updated to quartus 9.1 two weeks ago, our license manager (flexlm 9.5, shipped with quartus 9.1)crashes without any known reason. Does anyone have the same problem?

I found no information via Google!

Does anyone know how to fix it?

This is really urgent because we need a working quartus for lectures.

Best regards,

Frank
