eSata expresscard issue

I've been reading about Win7 freezing up and I too am experiencing the same issue. I'm running Ultimate 64 bit and I'm using a slim express card. This card uses a JMicron driver and may be the culprit. I downloaded the latest JMicron driver but my laptop still freezes up. When I leave out the expresscard, the laptop is fine.

Anyone have any clues or a fix?

Thanks all!

What model expresscard?

This is the model...

OWC Slim ExpressCard/34 to eSATA Adapter... (EXP34SATA2F1) at OWC

It claims to be compatible with both Mac and Windows 7
