Acrobat 8.0 - Cannot connect to Konica Scanner to pull down PDFs

[mdcr]

When we go into File/Create PDF/Scanner in 8.0, it allows us to choose a scanner, but the drop-down list of scanners is empty with no (apparent) option to add a new scanner. In 7.0, you could add a scanner by adding the IP address, but not in 8.0? We have a Konica Minolta scanner that will scan and send via email, but for very large jobs we scan to a local box on the scanner and have users connect via Acrobat and pull down the scans. Anyone else run into that problem? and a solution? Thanks!
