Error when opening paycheques.

When I try to open up payroll I get, "An unexpected error has occurred while signing in with your Sage ID. You must sign in again". All other journals seem to work.

- Sage 50 Premium Accounting. Version 2015

- There is also another version of Sage 50 installed on this computer, but that one hasn't been opened since I installed the one I'm using now.

- I took a class extension. The payroll licensing doesn't expire earlier than the program, does it?
