We have an Acer computer in which we loaded the Windows 98 upgrade onto. Two weeks later we got a BearPaw 1200 Scanner by Mustek. We did not have a Scanner port so we installed a USB port. Everything was going okay until windows asked for the CD-Rom then after putting in the CD the computer went into safe mode. If we take out the port the computer will not go into safe mode. Please help!! I really want to be able to scan some baby pictures into e-mail. Thanks
