Been using Vegas Pro 11 for a while and just noticed I lost my Audio FX. Tried uninstalling and reinstalling and restarting my pc. No luck so far. Any help would be greatly appreciated.
I had this happen recently when I installed then uninstalled the Acid Pro 8 trial. I noticed all the Sony effects looked different after installing Acid. After uninstalling, any Vegas project I opened had the missing fx error. When I found the Sony fx and tried to use them, all had an error about needing to authorize them, use a dongle, etc. Fortunately reinstalling Vegas 10 32bit and 14 64bit and reactivating reloaded all the Sony fx properly. I'm not sure what else to suggest if reinstalling and reactivating didn't help. Time to contact support.
