Why can't I open up Firefox 4.0 Beta again? One time only?

more options

Yesterday I downloaded a preview of Firefox 4.0 Beta 1 and had a blast playing with it but this morning I went to try it out again and now its just back to normal Firefox 3.6. I double-clicked the new 4.0 icon in multiple places, (i.e. Start Menu, Desktop) and still nothing just regular ol' Firefox 3.6.

This happened

Every time Firefox opened

I was running 3.6.6 on my XP computer and I can run both 4.0b and 3.6.6 just fine.

If you go to C:\Program Files you will probably notice that there is a Mozilla Firefox folder and a Mozilla Firefox 4.0 Beta 1 folder. Make sure you have closed whatever Firefox window you have open and then open the firefox.exe from the Mozilla Firefox 4.0 Beta 1 folder.

The executable files for the two versions of Firefox are different, so you have to make sure your shortcuts are aimed at the right one.

I have tried to download again and have got to the installation and when I am prompted to hit "FINISH" it locks up. It says "Firefox is not responding". I have tried three times. I quit will wait for your final release I suppose.
