Please use the bioconductor mailing list. This will allow other people

While I have commented on the usage of Agi4x44PreProcess and tried to
help people using it, I have never actually used it.
In this particular case, I would recommend that you read the help for
the function that you just used: ?read.AgilentFE.
I am 99% sure that your files were not "generated by the Agilent Feature
Extraction image analysis software", explaining why the function was
unable to read your files and giving you this error.
These files most likely originate from GEO. The GEOquery package will be
a lot more useful in your case.
You would then probably need to convert it into an RGList or a similar
object for the Agi4x44PreProcess package will be able to work.
I hope this helps,
