How do I revert?

[JJP]

I had 3.0.9 installed on my website then went to 3.5. I found things I cant run with 3.5 and a few bugs so I would like to switch back to 3.0.9. When I did all the uploads again for that version and started the upgrade it says this:

We have detected that you have already tried to run the upgrade script. You will not be able to proceed unless you revert to a vB 2.2.x/2.3.x database.

What do I do? How do I revert a database? How can I get back to 3.0.9?

You can't downgrade ... restore the backup you hopefully took before you upgraded to 3.5 or try to use impex to do a vb to vb import but im not sure if that will work.
