Can't install Propery Bee

[oxfordblue]

Hi,

I have property bee on another computer and have spent the past couple of hours trying to install it for my parents, using the various instructions here (profiles folder etc) but without success. The Wizard Screen appeared just once and I foolishly used my details which we subsequently decided was not going to work. Even more foolishly, I removed it and, ever since, have been unable to see the wizard screen. Restarts, extension deletions, removing traces through firefox have all been to no avail! If anybody could advise I would be most grateful!

Many thanks.
