(1) You shouldn't have to do #4 as it will remember the code, otherwise sounds fine, although...
(2) You can also get beta betas here, which will be more recent than the installer ones (when they're available) and (so far at least) can be used in parallel (e.g. just unzip the single file onto your desktop and run it from there).

Hi John,
Thank you very much for the quick reply

. If you're referring to the beta betas that Jim posts in the
Marine Aquarium 3 Beta NEWS & DOWNLOAD thread, I have tried that, but it asks for a user name and password, (I unsuccessfully tried the user name and password I have for this forum, but no joy

), without which, I'm unable to download the file. If there is a separate thread, etc., where the files are available, or if someone could explain how to get a user name and password for those files, I would be grateful! Thanks again, John!
