Welp, downloaded the update to try out 1.0 and i get that. Figures, so i completely uninstalled and deleted the starbound folder just to be sure and re-download, no luck with that, get the same error. Scoured the forums, but no joy, So here's the log...

Not the first time a starbound update didn't work for me the same day, oh well Edit* Source id made a smily, derp Edit 2* Ok, so i gave up for a bit tried everything ppl where saying to try... New sticky linked to Microsofts redistributel, uninstalled the one i had, installed the one linked. Via steam i get the exact same error, however NOW starbound launches through the EXE in the directory, YAYS! So it seems steam is having issues or something, although the first time i tried it gave me a access violation and crashed, 2nd time it worked just fine. Played through earth, landed on the starter world, got the 20 core frags and beamed back to my ship all without anymore access violations... Guess we'll see how it goes, will make another edit if anything changes.
