Strings Breaking While Re-Stringing

I recently re-soldered some of the connections in my Squier Vintage MOdified 70s Strat.



I did try to adjust the neck tension and height on the saddles. Now my 9 gague strings are breaking while trying to restring.



Is there some way I can set it back to default? Or am I screwed?:evil:
