John,
Well first, that PST download page identifies those drivers as being
for Windows XP/2000. I.e., those are old (and 32 bit) driver files,
and I would not expect them to work for Win7-64.
I would just do a complete fresh install of 2.0.10.242 or
.353. Installation should also ask to install the Port/SRBox
drivers, and you should say Yes.
I have EP2.0.10.242 running under Windows 7 64-bit. I got a Cedrus
RB-530 response pad to work as an SRBox on that machine, which means
that the the E-Prime SRBox driver must have worked there. I did not
do anything special to get it to work.
