i would definitely call/email them b/c last year i ran into some trouble with tmdsas too: they didn't verify my mcat scores (released in april) and post letters of rec (sent early and multiple times) until i harassed them a bit.
some TX schools said that the delay didn't matter because out-of-state applicants are evaluated last, but to the contrary-- a few days after tmdsas finally verified my mcat scores, i rec'd an invite from southwestern. tmdsas still hadn't posted my LORs at that time...but with more nagging (esp. since southwestern would probably need the LORs in time for my interview) everything got squared away.
if i hadn't checked up on them, i probably wouldn't be matriculating to southwestern in the fall, so yeah--it sucks, but it's worth doing.
