no I had not. Thanks for the link I'll take a look.
I actually can read the files now. The problem (which
I still don't understand) seems to have to do with a
networked drive. IDL must have timed out during the read
or something like that.

But now that I moved the files to the local hard drive,
they can get read in no problem.

cheers,
bob
