The reason I don't think that is the case is the announcement of the successful SWARM beta, and the launch of the new trading div. Had there been any significant SW issues, we would not have gotten that PR. Furthermore, any significant SW issues would (prob.) limit the desire to do indepth demo/training.
From the email that Paul Strickland sent Allie the other day, I doubt that 504 issues are in the future. I don't think he would have made such a definitive declaration about 504 financing if there was a possibility they would do it again.
I understand from posts here that Paul has been working on another source of financing.
