Some problems with launching

[Solar]

Hi, recently got some problems while trying to launch H&H on my laptop. I've got Ubuntu\Win XP dual boot, but:

1) While using Ubuntu I cant play cause the mouse replies to my actions with a huge delay, as if I was trying to play Crysis, though I think my laptop is good enough for running H&H.

2) After that I tried to launch in XP, but got an "Unable to launch application" error. Tried reinstaling Java and clearing Temporary Internet Files. I'd be very gratefull for helping me to solve at least one of those problems.

Heres the exception Java gives:
