I just uninstalled 0.9.8 and installed HandBrake-svn4978_x86_64-Win_GUI.exe. When I run the program all I get a a blank white screen. I also tried 4 previous nightlies and get the same thing. When I close the blank white screen, the following error is displayed:
An Unknown Error has occured.
System.NullReferenceException: Object reference not set to an instance of an object.

Since my last post, all nightlies have been the same, when opening the window is blank, when closing the above error is displayed. Am I missing something? Am using the Win64 GUI nightlies.
I just downloaded SVN 5024 (artifact: HandBrake-svn5024_i686-Win_GUI.exe) and am experiencing the same problem. Completely blank screen. When I close Handbrake I also receive the same error message.
I experienced the exact problem detailed in the original post with HandBrake-svn5021_x86_64-Win_GUI and with the very latest HandBrake-svn5040_x86_64-Win_GUI.
Since this problem clearly still exists, and no solution has been posted to this thread, I thought I would share how I resolved it.
Since the prior post commented that it worked fine on a "new PC", I figured it must be something leftover from the uninstall of 0.9.8 (or other prior installed version) that was causing a conflict. So I renamed %USERPROFILE%\AppData\Roaming\HandBrake to %USERPROFILE%\AppData\Roaming\HandBrake-old. Then HandBrake-svn5040_x86_64-Win_GUI started fine.
I did not debug what file or setting in the directory caused the problem.
If a developer would like me to post the contents of that directory I'm happy to do so. I'm also happy to help debug this problem with a developer if desired.
I hope this information saves others some hassle when upgrading to a nightly.
