I have a ScanJet 5370C HP scanner. I wanted to update my drivers and in doing so I notice the version of the updated driver is 2.52 (dated Feb. 2002). I already have that version on my system but I think it came with my scanner which I purchased in 2001. Should I not bother to download and install (if it ain't broke, don't fix it)? Also, when I attempted to install, I got a warning that a Microsoft Digital Signature did not appear on the software and so it might not run successfully. Any comments from those more experienced than me.

Thanks.
