Are you sure you uploaded all the new files to their proper directories? Specifically, /dbtech/vbactivity/type - those are the files that, if missing, would cause the issue you describe.
Another option would be that the filename column of the dbtech_vbactivity_type table wasn't populated properly. Could you please check that?
If that exists and the files exist, then please try clicking Repair Cache and see if that solves it for you
