This is not Adobe. Rather user to user. Visitors here like yourself. Classically, Adobe offers support for the latest version/purchased/registered. That is the way it is and has been.
Lots of troubleshooting paths to follow, but first the typical drill that I give Premiere Elements 8 users.
1. What computer operating system is your Premiere Elements 8 running on?
2. Are you running the program as the 8.0.1 Update?
3. Do you have the automatic background rendering and autoanalyzer disabled?
4. Does the problem exist with and without the antivirus and firewall(s) disabled?
5. Do you have QuickTime latest version installed on your computer with Premiere Elements 8.0/8.0.1?
6. Are you running the program from a User Account with Administrative Privileges?
Let us try the classical approaches and get more drastic, if necessary, as we proceed.
1. Delete the Adobe Premiere Elements Prefs file and, if that does not work, then delete the whole 8.0 Folder in which it exists
Local Disc C
and in the 8.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then you delete the whole 8.0 Folder
in which the Adobe Premiere Elements Prefs file exists. Be sure to be working with Folder Option Show Hidden Files, Folders, and Drives active
so that you can see the complete path cited.
2. If problem still exists,
a. Deactivate the program using an opened project's Help Menu/Deactivate. Close out of there.
b. Uninstall the program the usual Control Panel way.
c. Do a free ccleaner run through (regular cleaner and registry cleaner parts) to get rid of any leftovers from incomplete uninstalls reinstalls.
d. Install the 8.0.1 Update
3. If all else fails, create a new User Account with Administrative Privileges and install and run Premiere Elements 8.0/8.0.1 there.
We will be watching for your results.
