I just upgraded my new Averatec 6130 to XP Professional. Some problems: - with 13 minutes let to go in the upgrade I got error messages that it could not find the file msdart.dll - I just skipped these messages and completed the upgrade. Then I installed all of the drivers provided on the averatec website. - Now XP runs extremly slowly. Also device manager does not show any COM ports (just an LPT) & connection wizard does not allow for a dial-up modem connection. The modem was working fine before the upgrade. Can anyone give me some advice?
