it's unclear if you
did a windows system restore
or
a restoration to factory conditions
with back up disks
however, in any event if
you resetted all your system files
to square one, then it severed all
links to software installed afterwards.
this might be a good thing since
you discovered
1) something went wrong with a installed/unwanted/incompatiable
software
and
2) if you make sure and/or manually make
system restore points before installing
software you will have a little insurance if
something goes wrong
while this issue is still fresh for you
do some research with creating complete
harddrive/disk backups. I highly recommend
disk imaging whtich copies everthing to
a set of cd's rather than the old/standard
backup which compresses everything into
one large file,eg backup file.
look into driveimage xml. later if
you have a new question about backups
create a new post/thread on this particular
subject......
