Hi!
Sorry for the late reply, but I answered by E-Mail in July and just now saw that Google hadn't forwarded the mail. So here's my answer from then...
I never heard of such problems with version 3.3, but could it be you installed the wrong firmware version? Prior to 3.3 there were also firmware versions for the old Dual Strikes with ATMega8 microcontrollers and the SMD versions, which were for Gummowned's very small Dual Strike - so you might have accidentally used that.
Bye,
Michael
