Unable to view file. ID of server used for transport is

Unable to view file. ID of server used for transport is invalid.

I've upgraded my GroupWise 8.0.2 (with webaccess 8.0.2 11.12.2010) to 12.0.3 with HP1 with (webaccess 12.0.3 11/16/2014). After this when I login via webaccess, click Documents, then I press "Search" > "Fields to search" > Anywhere and it's ok for now and system finds all my documents. That is OK. But when I want to view some file, Excel for example I get this error:
Unable to view file. ID of server used for transport is invalid. Download file.
When I try to Download this file it downloads empty, size 0Bytes.
There is no problem when I upgrade to 12.0.0. It only happens when I try to upgrade to 12.0.3HP1 or. I also tried upgrade 8.0.2 to 12.0.0 and then to 12.0.3HP1 but with no success. Still the same error.
Could anybody help?

Chris
