FIngerprint scanner was working, now it is not!

So I haven't been having many problems with my computer of late, but now my scanner isn't really responding well. When i go to the control panel, i am able to use the scroll feature of the device (showing that it is working at least a bit) but i have about a 50% chance of using it to login to windows (sometimes it works, sometimes it doesn't) and to fill out passwords. My computer has been glitchy a bit more lately, did a bad vista update come out? anyways, if anyone has answer to this hit me up! thanks

 

after i did the last large vista update i think it was like 4912.. something like that it was supposed to speed up vista.. well i had to rollback that one really messed me up.. that could be your issue. my fp reader touchpad and video drivers did not work after that one

 

Have you tried updating the fingerprint software? The version that came with my machine had horrible memory leak which would affect performence.

The folks at UPEK support sent me a the new version and all is working well again.

I am not allowed to post the link to it, but you can email support and they responded to me within 24-hours.
