8432Ti firmware

Since I’ve updated to Mainboard MICORSTAR K7T Turbo2 Via Chipset and Athlon Thunderbird 1,4 GhZ (OS WinXP) many problems in burning has come.
With CloneCD, after Power laser calibration, plexto doesn’t come and I can’t burn.

I tried to updated plextor firmware, from 1.07 (original) to 1.09, but it was impossible: ““Upgrade Failed - Unspecified Error (00000)””

Do you know about this problem ? Why I cannot upgrade firmware ?
