Unhandled exception during variables download

Unhandled exception during variables download

Hello,
I am quite a new Zenon user and I currently started creating project for visualisation with Beckhoff CX1020 PLC. Everything is going well, until I'm trying to download variables from the controller. I'm entering AMS Net ID, port and I'm connecting with the driver succesfully. It also reads all necessary variables. But when I'm trying to save the variables, which I added, I receive the "Unhandled exception" alert:
An unhandles exception has occured, an error file has been written. Please send the detailed description of the actions performed which lead to this error-message including the errorfile:
C:\Documents and Settings\All Users\Application Data\COPA-DATA\zenon622\beckhtc32.txt
and a backup of your zenOn project to your local zenOn representative.
Unfortunately, currently I do not have an access to both: mentioned txt file and my project, but I tried the same operation on two computers and I have this error in the same place every time.
What could cause this error during the variables download?
My Zenon version is 6.22 SP1.
Thank you in advance!
