Use remote version of Act 22 synchronized on two machines. Whenever going to the contact tab I get an error message that Act has encountered an error. Please restart the application. If I close the error message everything works fine until I navigate away from the contact tab and then navigate back Get the same error message. Have tried several different layouts. When I change layouts I get the error message pictured. Close that and then back the original error message when going to the contact tab. No addins and identical files being used on another computer with no issues. Have uninstalled and re installed with no change.
You may have corrupted ACT preference settings.
Here is a link to how to have them changed -
