Error reading Association View Landys+Gyr

Hello.

I'm trying to read Landis+Gyr Meter (ZMD405CT44.2407) as i did times before with older versions of gurux DLMS. Now I encounter error when i'm getting the association view.

I get the following error: Unacceptable Frame 3 times in a row and then it shows connected but no object list gets created as it was in previous versions.

If I hit refresh button the error is more specficic as: "GetObjects Failed: Unacceptable Frame"

I got the same behaviour with 3 different meters from the same brand and the exact same model.

These are the last lines of the trace.
