Facing Troubles And Need An Advice

[Becharax]

Hello People :)
I've purchased in April an Mbox 2 Package which costed me around 750$ in my country. I registered the stuff and everything and benefitted from downloading the Pro Tools LE 7.4.

However, I have a Toshiba laptop A200-204 with the following specs:
Core2 Duo 2.2 Ghz
4 Gb DDR2 Ram
SATA Drive 200 Gb

and a Windows Vista 64 Bit !!!!!

The package never worked actually. I used it on another laptop with the same specs but with Vista 32 Bit !!
It worked but it was really really slow !!!!
i had to settle with 1024 Samples to get to run Xpand !!! and still i heard some clicks and noise and Pro Tools gave me some msgs that i should use higher buffer.
I dont know what to do ??
First what should i do with Vista 64 bit ???
Say I wait for the release of a 64 bit driver will i have to pay extra charges too more than I paid actually ???
plus what should I do to get to run my Pro Tools smoothly with at least 512 samples and get to run everything in it smoothly with no messages...
I am really disappointed.
Let me know please if anyone has something to say
Thank you

Windows Vista 64-bit is not supported. The current Pro Tools LE requirements can be found here.
