Sorry Ashley, the log is incomplete and finishes just as you hit Hotkey #1 to contact Tower. The problem is this, although PF3 continually writes to the debug log the operating system, in its wisdom, buffers all this log data and doesn't actually flush it out until (a) it's ready to do so or (b) PF3 is closed properly. By closing it with task manager all the buffered data is lost unfortunately.
I understand why you closed it with TM and the reason why PF3 seemed to be 'stuck' was it was simply waiting for you to clear the active runway. Once you're instructed to 'report when clear of the active' PF3 goes into a semi interactive loop. It does have a couple of fall backs... after 2 minutes you will be reminded to clear the active and after 5 minutes it will drop out of the loop and the close you initiated will complete. I know this all seems a bit complex and frustrating but it is what it is. If you at least wait until you get taxi instructions to the gate before closing PF3 then everything will be great.
Sorry I can't help more than this but the precise moment you say you lost contact with ATC is exactly where the log ends.
