Strategy Tester: Waiting for Updates - pls help

 
Hi everybody.
I wanted to test an EA in the Strategy Tester (EUR/USD), but I just get the message "Waiting for Updates". I am able to test it from 2001 till today but if I want to test it from 1.5.2001 till 31.4.2002 I get "Waiting for Updates".
I already downloaded all available historic data from the history center, but nothing has changed.

Does anybody has an idea how to fix this problem?

Thanks a lot & Greetings
Paci
