Problem: Calendar Missing Dates

The file mscal.ocx has been overridden by another program and the version that was installed is incompatible with MPOS. To resolve backup your data and enter the control panel and select install/remove application. Try to repair the MPOS installation. If this does not work you will need to copy the file from your installation CD. Browse the contents of the MPOS disk and find a folder labeled "System32" find the mscal.ocx file and paste it into your local c:\windows\system32\ folder then restart your system. Keep in mind that if you start the program that copied the files over initially it will attempt to repair itself and copy the incompatible file over again.
