Thomas,

This problem ("stmgr has caused in error in WINTRUST.DLL") has now been
confirmed as being due to a damaged Win Me catalogue.

A fix that has been shown to work is to rename the folder
C:\Windows\System\Catroot to C:\Windows\System\CatrootOLD and then reboot
your PC.  This should hopefully fix the problem.  I would then recommend
that you reset system restore and make the following quick test.  Note
however that Win Me's
system file protection will not be as effective as it should as it will no
longer have available the reference information it requires from the
Catalogue.

To reset System Restore:
System | Performance | File System | Troubleshooting and check "Disable
System Restore", Apply and IMMEDIATELY reboot.  This will flush you
restore folder and erase all checkpoints, then,
System | Performance | File System | Troubleshooting and uncheck "Disable
System Restore", Apply and again IMMEDIATELY reboot.  This should now
automatically create a new checkpoint immediately following the restart.
Finally adjust the space allocated to the restore folder,
System | Performance | File System | Hard Disk and adjust the restore
slider to your preferred setting.  A  figure of 200MB is normally more
than adequate for day to day use allowing perhaps a week of checkpoints to
be available although increasing this to perhaps 400-500MB for a few days
during periods of large installs such Microsoft Office is advisable.

To check the operation of system restore:
a) Create a shortcut on your desktop to a file.
b) Create a manual checkpoint
Could you create a checkpoint?
c) Delete the shortcut
d) Restore your PC to the checkpoint you created.
Was the shortcut restored?  Did you see any error messages?
e) Reboot your PC
Was the checkpoint retained?

Regards,
