fatal exception error in VXD IFSMGR (04) / VXD NETPPTP (01)

When I try to acquire a scan I get a "fatal exception error in VXD IFSMGR (04) +00012a3c". The graphic app. freezes. If I use CRL Q to acquire (CorelPaint) then Windows reboots!

I have no other problems with the pc. A previous error message said I had a "fatal a exception error in VXD NETPPTP (01) +00000EE5".

I've reinstalled the scanner software and re-installed W95. No luck.

 

Since posting things have gone from bad to worse. It won't shut down Windows properly and it won't load up windows in normal mode, it hangs just prior to Windows loading. The system said the scanner is operating normally but I disconnected the scanner and Windows now loads normally. I've overwritten the scanner setup once, what else can I do? How do you remove all traces of the scanner software so I can do a reinstall. It's a Microtek 335CX, if it helps.
