Problems flashing 6310i, cheap flasher,

I have several nokia 6310i phones with varying software faults, so got myself a cheap flasher (DCT4 flasher from ucables)

I am running into errors when I try and flash any of these phones with any software version, always getting the "Access violation at address 0043c54f in module...."
have tried several different flasher progs all with same result. (Windc24 2.0 / DCT4v30 / DCT4 Flasher v1.25)
have also tried switching to another machine with win98 (normal system is win2k with userport)

I have tried all variations of the fia files that I can find, and only the latest ones produce this error (all older ones produce invalid flash descriptor received) so I assume that this means that the wrong fia files are in use.

I'm not 100% sure of this but i think that cheap flashers require patched flashes in order to flash correctly... and i vaguely recall seeing some for 6310i

EDIT:
Yep, china flasher needs patched flashes (and i have some :-P )

is there any chance of letting me have a copy of the patched files (4.80 / 5.10) via email.
