Ok, I opened WMM to edit a clip from a TV show and this popped up. How do I fix it? Do I need a new MovieMk file?

Look at the Bricopack F.A.Q.

I did. It says nothing about it

--------------------------------------------------------------------------------------------------------------

PROBLEM: Windows Movie Maker does not function properly

SOLUTION
First, you need to uninstall the Bricopacks. Then, you need to install it again. But when installing, select the Custom Install option. There, do not check the Movie Maker option. Remember to check all the options you want. After the installation, Movie Maker should work.

Thanks. I'll give it a try ^^

This correct? (Just wanna be safe ) :

Yeah, that is good.

Alright. It worked. Thanks

Now that it's solved, may I ask what program you use for the Transparent windows?
That dosen't look like TT to me.

Your Wrong . It is TT. I just selected Skins>Aero 2.

Then how the hell did you get transparent windows even when they're maximised?

Also, link for Aero 2 please.

Do you have TT? If so look in your taskbar. Right click the TT icon, select skins, and select Aero 2. For  transparent windows even when they're maximized, I don't know what your talking about. Where do you see it? Are you referring to my Taskbar?
