XF 1.3 Uploaded 1.3 upgrade files and now forum setup is wiped

[Samus4145]

Last night I decided to upload the xenfor 1.3 upgrade files. The first time, it told me I can't upgrade because the files I have are newer than the upgrade files.

The next time I let it upload overnight and when I logged on this morning and tried to run the upgrade URL, i am presented with a page telling me I am ready to install 1.2.4 and need to enter all the mySQL database information once again.

What can I do to restore everything back to normal?

For anyone else reading this, using the full .zip to upgrade an existing site is a bad idea, for the reasons mentioned.
The upgrade .zip must be used.

The upgrade instructions are here: http://xenforo.com/help/upgrades/
As long as your FTP application is set to merge and those instructions are followed, you will have no problem.

Just to quickly followup, I also tried the upgrade package on my local server used for testing and it had the same issues, so my current setup was just completely incompatible.
