Recently active problems in Adobe about Flash

I just reinstalled Flash Media Encoder 2.5 after doing a recovery. And when I went to use it, it won't let me use any of the video settings. All of the video settings are shaded in gray. It will only let me use the audio settings. I tried to run the repair on it in add remove programs. and it said adobe has encountered a fatal error and is unable to repair Flash Media Encoder. So I just removed it, and went back to adobe.com and downloaded it again. And its doing the same thing. I went ahead and tried to broadcast and it did but just audio. The video was showing up as a blank white screen. I have been using Flash Media Encoder for almost a year now, and I have never has a single problem with it.
Can anyone help me with this?

Why does the autohide of a skin of the FLVPLayback Component not work when embedded on a website. (with no empty flash boarders)

I am trying to update Flash on my MacBook Pro (OSX 10.4.11). The install goes about 2/3 of the way through, then is unable to create 'the file' because 'You do not have the required access privileges.'

I'm the only user, this is my personal laptop. All browsers either came preinstalled or were installed/updated by me. I do not use a separate administrative account. What gives? How do I get Flash updated? The knowledge base article does not address the problem, since there are not any other users on this machine.
