Can't generate SDS from template

I am having difficulty with several tasks which involve generation and viewing of documents. I receive the same error message when I attempt to:

1. Generate an SDS from a template.

2. Upload an SDS.

3. View a previously uploaded SDS.

Each time I receive the error: Could not upload file to front end.

I have access to 2 versions of the SAP EHS work environment. These tasks work fine in one but not the other, which makes me wonder, of course, what is different?

I am running the 7.3 GUI through a VPN connection remotely.

Any help would be appreciated!! I'm starting to pull my hair out over here and it's not pretty!
