I think we are all talking about two different products at the same time. Getting a little confused on which product you are asking about.
Instead of using the terms new forum old forum. Refer to classic or threads when asking a question.
Since this is a classic forum.

As far as colors in threads you can export the style in the control panel.
Wipe the threads install. except for the export file.
Then start from new on threads and import the style back. Poof done. the export/import style process is just a simple download/upload process.

Being locked out of threads, you can use the lost password feature.
Being locked out of classic, Gizmo and I have already told you how to find it.
