#2 I need assistance

[Gerald Isaacs]

I have attempted to install Chess Club Central, using the instructions in the Readme file that I downloaded with the app. I have used MYSql to enter the initial ratings for about 25 chess club members and then I entered data for approximately 20 games after our chess club meeting. But when I look at the results, I see that no ratings have changed. So what do I have to do now to make the program recalculate new ratings based on the results of these games?

I desperately need help from anybody who is willing to give me a hint.
