Error(s) when trying to push to drivehq via ftp.

[ChrisM]

Hi,

I have been using bzr quite happily over the last few months to maintain a
project on my local Windows box, but my attempt to create an on-line repository 
with DriveHQ have not been successful. Specifically I get the following two 
errors when pushing via ftp:

bzr: ERROR (ignored):
'ftp://sea_of_cortez@ftp.drivehq.com/Projects/rezyn/.bzr/repository/upload
/udums79bb150foix0v3r.pack'
bzr: ERROR: Generic path error:
'/Projects/rezyn/.bzr/repository/upload/udums79bb150foix0v3r.pack':
: unable to rename to
'/Projects/rezyn/.bzr/repository/packs/86ad259002570d03f719acb6cfc3cb04.pack':
553 Error, Rename only works in the same directory:
"/Projects/rezyn/.bzr/repository/upload/udums79bb150foix0v3r.pack".)

What does this mean? And what might the solution be?

Many thanks in advance,
Christopher
