I've installed Phone Manager Pro 3.0.16 on a new laptop running Windows XP SP2! Phone Manager pro worked properly including accessing voicemail. The following day when the user attempted to access voicemail they got the following error. "sx801c.ini file was not found". I verify that in fact the file does exist in the Program Files/Avaya/IP Office/Phone Manager directory! I've uninstalled/reinstalled Phone Manager pro several time but we continue to get the same error. Does anyone have an idea how to fix this problem?
