hey, kilroy - you ever get AE installed? or is it still having this issue? I don't know how to fix it or anything (I have no clue what that error means), just keeping my fingers crossed for ya!
So, it seems all the plugins I used to have are still working fine in CS3!
Even some really old Composite Wizard ones.
But, I discovered they stopped supporting BMP sequences as a rendering options. Which is really strange to me, but, whatever. I used to like BMP sequences for making viewport background sequences for using in Max. Guess I'll just go back to Jpgs.
Also, Keylight's Despill and Alpha Bias controls are still color picker boxes. I don't like that. It's been like that since 7. I really miss the 6.5 slider controls. (I'm sure you all are like, "yeah, whatever, like I EVER used those!", but I did. Alot.)
