Try "System Restore" first, pick a date immediately before your first issues and you could login, it will put your Windows 7 back the way it was on that date (anything done after will be lost).
You might try "Startup Repair" after if the last date before you have been locked out is too far in time and you might lose important information that way, although, considering the problem at hands I don't think that will work.
Sure, report back, I'm curious to know how it goes. I also really want this to work, I'm a persistent person when I know what I'm doing.
