Vegas pro 11a?

[Derek Moran]

They are releasing updates with Build Number changes.
The original release (the one you have) is Build 370 for 32bit and 371 for 64bit.
Have a close look on the download page – the build numbers are now:
424 for 32bit
425 for 64bit

For whatever reason, Sony called this release “Vegas Pro 11 Build 424/425” (424 is 32-bit and 425 is 64-bit).

Thanks guys. I guess the changes are not big enough to warrant a letter suffix, but I missed Sony’s advice about the “update”.
