I suspect there is an implied "+1" in front of (520), so calling
from the UK is not really an option.  However ...  Have you tried
compiling more than once, and seeing if the problem disappears
on a second or subsequent run ?  It seems to me that if there
is an error in an auxiliary file, and you can persuade the
compilation to run to completion (by entering "s" for "scroll",
"q" for "quiet" or "b" for batch" in response to the error prompt),
the problem may be capable of rectifying itself without a need
to manually delete the auxiliary files.

Of course, I may be wrong (I frequently am).
