Just got it last night, 64 bit works great, but if I try and open the 32 bit version it just sits there on the logo box saying "Iniitializing DirectX plug ins".
Funny you should mention this... I've been using V10 64bit since it was released, but I just downloaded V10 32bit because I wanted to try out my Magic Bullet Looks and Sony Cinescore with V10 32bit. It stopped loading at the same spot you mentioned (at the DirectX plugins).
I'm going to try removing/re-installing V10 32bit and a few other options; if successful, I'll re-post.
I've been doing google searches on this... it appears that the problem may be NewBlue plugins. Do you have any plugins by NewBlue?
If you have the NewBlue plugins, here's a quick test I just performed: Before trying to open Vegas V10 32bit, in Program Files (x86)/NewBlue folder, rename the NewBlue folder "_NewBlue" and then just click Enter. Then try to open Vegas V10a, and it just opened for me. I then closed Vegas 10 32bit, renamed the NewBlue file to the original name, and then tried to re-open Vegs 10a 32bit... no luck. Not sure why or how to proceed further, as I really don't want to delete the NewBlue plugins and reinstall everything. Anyone else run into this?
You are a genius sir. I'm not even going to ask how you figured out that tinkering with NewBlue (yes I have it) would straighten out DirectX. Bottom line: It's alive!
