Broken PDT install in Eclipse Luna

Question

I am an Android and PHP developer, so I am trying to use Eclipse for both. I have my Android development up and running, no issues (Eclipse Luna). When trying to get my PDT to work as well, I create the main and library projects, but every time I try to open a PHP file, I get the following warning:

Plug-in org.eclipse.php.ui was unable to load class org.eclipse.php.internal.ui.editor.PHPStructuredEditor.

I have looked around here and online, and although there is some info on the error, nothing seems to help. I've tried the clearPersistedState flag, I've deleted (contents on disk as well) the projects and recreated, completely uninstalled and reinstalled DLTK & PDT. Any ideas what I can do to get PDT working in Eclipse?

Thanks for any help or suggestions you can provide.

Below is the full error details and Eclipse install info.

Answer 1

I had to completely remove Eclipse, re download a fresh version and install all software from scratch. Now I have both Android and PDT working. I hope this problem does not come back later.
