Mega 5.0 keeps crashing

[EpicHalflife2betafan701]

I just downloaded the new Mega 5.0 but it keeps crashing after installation help me PLEASE!

over here its worse, it crashes when i try to launch the installer, basically i run the autoplay program and after selecting the install option it just gives me an error

...ok nevermind, i was using another program to mount the iso because i couldnt see the option to do it with windows itself. I finally figured it out, and after running the installer through the built in mount option it worked. btw i wish i could help with your problem, cause i dont really know why it would crash for you, but just so i know, if you had the old mega build, did you install 5.0 on top of the existing one (4.0)?

You don't need Mega Patch 5 if you have installed the Mega Build.
Mega Build has the Mega Patch pre-installed.
