Unable to Restore Company from Provider bbk - Sage Premier

SUGGESTED

SAGE FAS Premier - I received a bbk file from our 3rd party provider who used FAS to do some depreciation work for us. We have since purchased our own instance of FAS and are trying to restore the bbk to complete our 2020 fixed asset work and I am presented with the following errors: 

Then once I click "OK" the restore resumes for a moment, then stalls @ 24% in progress - see below. 

We tried this over VPN, thought that might be the issue so I came into the office on the ethernet to our company's network to no avail this made no difference. Is this problem on our end as in our IT department during the install and setup? Or is this a bbk issue to which I would need to go back to our 3rd party provider? 

Appreciate the help!
