Thank you for all the responses. Fortunately was able to load last saved game which was with 2 games left in regular season of 1976. So I'll just replay game from that point forward.
The positive is now 1976 KCR has opportunity to do better this time!
I'm using the OOTP expansion, which is awesome. Really like how Expansion Draft was setup for entering TOR and SEA. Be fun to do that again.
I received some good tips and suggestions on the Report Bug Forum and most likely reason for problem seems to be:
1) computer crashed and had to be restarted the last time all teams were there.
and/or
2) For first time I downloaded several logos into the logo folder. So maybe one of them was bad.
Thanks again for the responses.Now it's back to 1976, where KCR has a 1 game lead on OAK!
