just a bit concerned?

I am getting just a bit concerned, I have rang the company four times now to try and talk with LF, I get as far as Wendy Townsend, she says she will pass the message on to LF and get him to ring me, but I am still waiting, why haven't we seen any movement on the second 510K? there seems to be still no enrollments in the burns trial? and then there is BARDA, is there a problem? perhaps we are just about to hear something decent and that may be the reason for the lack of info? if that is the case? then I understand?
But all of the silence is killing me, but it is killing the Share Price even moreso.
