Are you able to run reports ?

Anytime I try to look at orders >sales reports all I get is this;

Fatal error: Maximum execution time of 60 seconds exceeded

I can't change the execution time so just wondering if the is anything else I could do to at least see what these reports “report” I'm guessing not much.

Pretty sure they don't tell me how many people used a voucher or where the were reffered from. Cscart seem to lack anything usefull like that.
