The DroverLords....

Welcome to the forum.

DroverLord controls the workspaces.  Try changing/resetting your workspaces.

Try updating your video driver.

Time to tell us more details if we want to help you. See: Adobe Forums: If you need help quickly... Guideline...

I just started having troubles with Premiere CS5.5 and the 'DroverLord' issue as well.  Premiere is crashing at random with the error message "Sorry, a serious error has occurred that requires Premiere to shut down.  We will attempt to save your current project" (or something along those lines).  the 'DroverLord-Tab' process shows up in the task manager after each crash, which is new.

I've tried scanning for viruses, resetting my workspace, updating my video drivers, repairing my installation, and it still keeps happening. 

The only change I've made to my computer recently is connecting a set of speakers, but I've since removed the speakers and it's still happening.

Putting on my deepest , slowest, graveliest (whiskey) voice...

"THE DROVER LORDS"

What a great name for a movie (or a novel).

Love it.

Amazed that a programmer came up with something as cool as that!

Uninstalled PPro, no luck.  Uninstalled entire CS5.5 and it worked for a few days.  Now it's back.

It seems to be something with the workspace or tabs layout.  I have a custom effects bin with a few transitions and effects that crashes Premiere when I hover over one of the effects.  Every time. 

Is there really no answer to this?  Nothing like working until 1:30 in the morning with a crashy program.

Or, a rock band comprised of Adobe engineers?

... custom effect bins... That might be it.

Story goes.

I didn't have any problems.

Custom effect bin + effects.

Week - 2

DroverLord

Uninstall & reinstall

Nothing changes

Uninstall with "delete settings" & reinstall

Works

Again custom effect bin.

Same thing (DroverLord, uninstall with settings, reinstall)

So, I'll try, does it work when not making custom effect bin.

I'll report after a week.

At least now it works

I deleted my custom effect bins and haven't had a problem since.
