Not every version is kept around. You could try to see if 2.9.1 is
part of a stable Bioc release. But in general I am not aware of how
you can get any arbitrary old version of a package. When you have the
tarball use
# R CMD INSTALL limma....
from the command line (and if that is not enough, look in this email
list, the manual and the faqs for the numerous help available on this
subject).

If you read this message carefully it seems that limma is looking for
some columns in the file which does not exists.

Coupled with this warning I guess that the first characters in your
file are non-standard for example using a different alphabet or
whatever.
You should look carefully at the file in order to see what the error is.
It could also be the local you are using: is he using english and you
are using a different language?

Perhaps, but I doubt it.
