V7 Matrix Infinity Install problems - not working?

[TarzanBoy007]

I installed a Matrix Infinity today. I get the Infinity 1.2 logo right by the playsation 2 one when I boot an original game.

-Direct boot (hold down select) works
-Original game works

-Configuration menu (hold down triangle and circle) does NOT work. If I select this, then the PS2 goes to a black screen and just sits there.

-Backup seems to NOT work. It spins the disc up and then gives me the pink/red 'please insert a ps2 disk' screen. I tried two backups (niether have been tested). A cd copy of Tekken Tag Tournment which I burned(4x) using alchohol... and an HD loader cd i burned(48x) to cd from a downloaded image. I used Memorex 52X CD-R media

I also had a problem with the SCEX point. The first wire i soldered to that point fell off, and I had a hell of a time getting solder to flow onto it to attach a new wire.

I would appreciate any and all help.
I am going to put photos of my install (sloppy wires, i know) up at
