“CaseWare ERROR Error # 630 “

Hi to all the nice people at Techyv!
I'm using a USB Broadband in most of my surfing hours.
I used to have a DSL Connection but not possible now because of travel and projects.
I think this is a major reason, if not exactly the reason, for this error in Caseware.
Am I correct? How can I fix this and continue using the broadband?
Thanks people!
