Dear Jack,

It is considered wise to explain all the elements of a problem when seeking
help.

There are many possible causes for your problem, but not knowing exactly
your instalation, it will be very difficult to help.
I can imagine several possible missing elements in your above text, but
instead of be guessing, why dont you tell us what is in between your PC and
your 8535?
