I've been trying to run x-plane 9 beta 11 but after about 15 minutes of flying I get an error message regarding BAD_ALLOC at HL.THREADCPPLINE 301. Any ideas?

First get the update here http://www.x-plane.com/pg_downloads.htmlUse the update installer if you have the full DVD version. (I'm guessing you have a first release DVD set)Current version is 9.67Current beta version is 9.68

I've downloaded 9.67 but have not yet had chance to play it for a long period of time. Having 2 teenagers at home will do that :(. If it works ok, I wont respond. Otherwise (in TERMINATOR VOICE) I'LL BE BACK!!
