also, now im getting unsupported file error when trying to import .MTS files (AVCHD) from Sony HD camcorder.
Go to the new sequence dialogue box. If there are no MPEG presets (HDV for example) your installation has been reverted to the trial version.
If Huntrex is correct, and this happened to quite a few users with the 4.0.2 update, and seems to still be around with the 5.0.2 update, as well, here are the steps to correct this:
1.) De-activate (if possible)
3.) Run the Adobe Clean Script CS5 several times, re-booting in between
4.) Perhaps run a Registry cleaner, like CCleaner (PC only), or similar for the Mac
5.) Install CS5
6.) Instantly update to CS5.0.2, before launching
7.) Now - launch and test - you should have all MPEG functions and HD Presets back
Do i have to reinstall ALL the adobe programs that updated?
