Long story short, and I thought I tested to make sure this didn't happen, but long story short I created a loop with a [loadbang] object inside a subpatch that renders me unable to open my .pd file in pure data. I have opened the same .pd file in notepad. Does anyone know how i can delete the subpatch holding the loadbang loop from inside notepad?

seems like you could delete all of the text in between "#N canvas ..... name-of-subpatch" and the immediately following #X restore ... pd name-of-subpath (including those lines)

There is a -noloadbang command line option that should solve your problem :
