VB help.. Trying to install and tell me i have to upgrade?

[Team_RCRR]

All-right i installed VB 3.7 C2 and i tried to install the CMSP or something like that (the Portal) and i screw my self by not really paying attention and just clicking. So i rest the file paths for ALL my images. When i deleted all the files in FTP and re uploaded 3.6.9 it says i have to upgrade! I though i deleted it all? please help! It cant run the installer script for a FRESH install.
EDIT:
I want to install 3.6.9 as the 3.7 was only to see whats up with it.

You can't downgrade, which is why you have to upgrade. The only way to downgrade is by restoring a database backup.

I never backed up? Ill re config it.. God i feel stupid... Lol sorry bout that.

What version does it say you are running in your vB admin control panel?

3.7 I just re configured. So i going to run 3.6.9. I guess i had a stupied moment, sorry.

If it says you are running 3.7, then you cannot downgrade to 3.6.9, unless of course you restore a backup.
