CST error message.. Solver run aborted due to memory exception.

Hi, I installed CST 2010 about a week ago, and I tried running a simulation of a model, which I ran in CST 2008 in CST 2010. The frequency range is a bit wide, 0.1MHz to 9GHz(and it worked fine in CST2008.) But it showed this error message and I couldn't get any far field patterns.
The error message is Solver run aborted due to memory exception.

I am using windows7 and 3.5G RAM, 3.16GHz dual core processor, if these could be any information to resolve this situation.

Is there anything I can change? Please help! and thx in advance!
