PDFMaker Files missing, know fix, but RECURRING PROBLEM!!!!!!!

See subject. In detail, the steps listed to fix this problem work, but every so often, like monthly, the issue happens again. We use adobe professional 8 among six users along side office 2003 business, and one user has this issue happen repeatedly. What gives? Why does this happen in the first place, and what can be done to prevent it? Is her computer just too slow, and sometimes when word loads the plugin things take too long and the plug in times out? Does an update invalidate the plugin and the whole system just needs to have the module reloaded? Why does this happen to one user? the only thing that differs among the users are the hardware specs.

Thanks.
