Ok, good, you have the latest version of direct x installed.
Now go to add remove programms in the control panel and uninstall
all the plugins that you had in Vegas, (at the same time you can
again uninstall Vegas 10 and 11) whatever you cant uninstall from there,
you go in the program file (c:/program files) and delete them.
And at the same time delete all folders pertaining to Vegas.
(I hope you have backups of all your plugins and software)
Make sure also that the new Direct X is properly installed.
Restart your computer…Install Vegas 11…Open up Vegas…and let us
know what happens.
If that don’t work…Another step will have to be taken.
