Cricket2007-Vista-SonyVaio

The game EA's Cricket 2007 runs fine on Windowx XP on my HP Pavilion PC....... but today when i installed the game on my sony vaio C-25, the game started gr8 but the arrow keys are not responding to angled shots(most of the time, it played once or twice, else the batsman kept leaving the balls)....... playing in single direction works gr8 though......... 2 simultaneous key presses for arrow keys not working, that is..... i guess it would be true for any other game also........

Please somebody out there clarify.... my laptop has vista home edition @core2 duo 1.66 ghz, 1gb RAM, nvidia geforce7400.....

Anyone has any solution or sugestion?????
