Code ceases working after months, PC only

Question

Hi,
Apologies for the cross post.
We have a project that is running on Mac and PC, swf's that
are loaded into a Director player. They were published
November/December 2005 in Flash MX. All Director Xtras are packaged
and installed with the project, as are four libraries necessary to
create a fast start projector.
The swf's tally some results in an object, which is passed to
a method that creates a string. The break is in the method, where I
do a split and check the result (tmpvar == "TM"). The project was
professionally QA'd, as well as inhouse, and by our client. We also
have a good store of data from the time the project was launched
until late July that shows the work has been functioning without a
hitch.
We received reports that the swf's stopped successfully
reporting late July/early August, only on some PC's, and only PCs
running WinXP (not all, either). Has anyone else had a project that
has inexplicably gone awry in the last month or two? I am able to
replicate the problem only through the Director authoring
environment (the project runs fine here on XP, of course), but as
soon as I republish one of the offending swf's, the issue is
resolved.
Does anyone have any suggestions on what could be causing
such an issue? We are facing having to reburn a GM and redistribute
new CD's, a quite expensive exercise.
Cheers,
ck
