Dear Nathan,
please excuse the delayed reply. The answer is yes. You can import a
wide variety of probe-description files by adapting the function which
is given to the 'makeProbePackage' function by the 'importfun'
parameter. Have a look at the default 'getProbeDataAffy', this is a
function that works for the "normal" probe_tab files. Its (simple)
commented source code is available through the source packages
(.tar.gz). I recommend using this as a template and adapting it.
You can use "options(error=recover)" and the debugging browser of R to
see what exactly is going wrong with your file. I am afraid it is
difficult to tell for me from the information you provide, and I
suppose with a little bit of basic R knowledge (maybe ask a local
guru)
you should be able to trace this down.
Best wishes
Wolfgang
