How can I release my 401K funds?

I left my employer in August 2009 and had a 401K plan, 100% vested, that I participated in for at least 7 years. The employer was in Miami, FL and sold their business to a Michigan based company in November / December 2009. My plan was administered through Trans America. June 7, 2010, I completed paperwork to roll my fund over to an approved self directed IRA fund through my borkerage firm of Edward Jones. The last 3 weeks, Trans America acknowledges receiving my paperwork for roll over, but states that the plan stipulated the ex-employer who no longer exists, has to send over a release form. There is one administrater left from this ex-employer who my brokerage firm has been in contact with. The administrator has said they do not have the form, thinks there is a freeze on funds, is not aware of the problem - in other words is being uncooperative. We went back to Trans America and apparently they have also been requesting release from the employer without response. I have also done some digging and know of one other employee with the same problem (they now work for the Michigan company). So, how long do I have to wait for a resolve on this situation? My broker has obtained a copy of the release form and is going to try to reach the administrator on Monday, but I wonder if there is a bigger problem here. Do I need to call the department of labor at this point, or do I have to wait a longer period of time?
