A couple of suggestions;
Check with an RE attorney about filing a "Notice of Interest" on title while you sort this out. This, along with a strongly worded letter threatening a suit for specific preformance, and other actions, should get the attention of any seller. The NOI could delay or even prevent them from selling to anyone else - while you work this out - but could also backfire if you are out of line and have colored title improperly. A full blown suit could be costly and might be over kill as first step.
You need to make sure you are in good form with your responsibilites under the contract. Check and double check that you are in full compliance with the contract & be ready to close on time. If you miss your closing deadline you might not have much to complain about.

I have used Michael Coad for over ten years now and I wouldn't consider using anyone else. Give him a call and I am sure he will represent you well.
