[AMSAT-BB] SatPC32 question

I updated my Kep file but I did something went wrong. Now when I start the program I get the message, No source file was found for the group Standard. Please select a source file for this group after the OK.

Where do I find this file? I have been using this program for many years and never had this problem before. Any advice would be appreciated.

Merry Christmas
