usb to serial adapted (dongle) problem

I got a freeduino serial from supplier in our country.
It works on my friends old pc which got serial port.
But i got a converter from BAFO with prolific chip.

I tried in xp and vista( but vista is courpted so as i installed there is blue screen of death)

I tried various driver ver. specifically mentioned in sparkfun's comment of usb to rs232 dongle.

Is some ver of driver work or other OS like Linex.

In xp its give following error

The I/O operation has been aborted because of either a thread exit or an application request.

They said it dont work with converter

Help guys ( because you rock )

hey any body

i think it is driver issue... I use several arduinos with serial Poroflic reductions...

I finally stuck with driver directly from porofilic

please send link to driver
