This Short Sale has hit a snag.

After about 6 weeks of working a Short Sale. I have just found out that the 2nd Mortgage( Real Time Resolutions) has rejected the 1st mortgage's offer. Now what should I do. The 1st does not communicate via e-mail and the 2nd will not pick up the phone, and seems to only e-mail on Fridays. I have a very qualified, and excited buyer. The 1st is HOMEQ Servicing and they have been great. If any one can help I'd sure appreciate it.
