okay, im sorry if this is in the wrong section, but i am in desperate need of help. i install the latest jungle flasher, portIO32, and put the necessary firmware in the correct folder. once this is complete, i use the ck3 PRO, and the PROBE to flash a 7 series liteon drive. the first goes succesful, no problems at all. then when i go to do another, it freezes when i press the dvdkey32 button. i can switch the ck3 off and back on and it will complete and return with the status "serial data is bad". so i figured that maybe something was wrong with the drive? WRONGO, the next 7 series does the exact same thing. so i reformatted windows, and it does the flash perfectly again. then when i do another, it freezes again. somebody please give me some suggestions.
here are my specs:

MOBO - ASUS P4P800-VM
PROCESSOR - INTEL P4 3.0ghz
VIDEO CARD - HIS ATI HD 4670
HDD - WD 2.0tb
RAM - 4.0g

Thank you.
