You received the latest update to ACT! 2007 9.0.1 and now your ASDS Product generates an error regarding a DevExpress component missing or it won't load.
You will need to run a repair on the installation of your ASDS product. To do this, go to Control Panel, Add Remove Programs. Select the ASDS product that is giving you the error. Choose "Change". When the wizard comes up, choose "Repair". Once that completes, choose "Finish". Now load ACT! and try your ASDS product again. This should take care of the problem.
