It's very unlikely that adding a few inbound links from a remote directory depressed your PR.
It's possible the switch to ColdFusion had an effect if Google dropped your old pages because they no longer exist, but hasn't spidered the new pages. Do the cfm pages have query strings? They will probably get spidered, but may not rank as well as straight html pages.
I'd study my backlinks and indexed pages for clues.
Welcome to WebmasterWorld! :)
Lots of the sites I monitor on a regular basis have suffered drops in PR over the past few months (as rogerd pointed out, this could just be a toolbar malfunction, though)
PR5 to PR3 seems to be a common story!
Are your positions in the SERPS/traffic levels suffering? The drop in PR hasn't made any real difference to the sites I have stats for.
I'm not expert, but if, for example, your actual PR was
5.0000000021 and today the actual is 3.9999999998,
the changes and perhaps the loss of any significant (PR wise) links could result in 2 level drop that's actually
a hair over 1 level.
Another factor might be that if instead of losing,
you did grow, but you grew at a lesser rate than numerous other sites.
I seem to recall reading that the total available PR is finite. As new sites come online, and as established sites grow, shrink or disappear, the redistribution of PR means some sites (appear) to hold ground, some gain, and some lose ground.
I've seen a bit of our shoreline roll out with the tide as well this summer. Some of this is from slower growth perhaps, but undoubtedly some of it is the result of less than careful shuffling of my own feet as I wandered along SERP beach.
