I'm not sure if it's the same version, but this version of swype for the evo works flawlessly. Here's the link:
New Version of Swype for HTC Evo | Market 4 Android
Make sure you uninstall any previous versions of swype that you may have installed first. It required a reboot after I installed it.

I just had the same problem (after wiping data and cache) I tried downloading everything but I got it to work by downloading voice search (google app). It works now.
I logged in and downloaded the installer, downloaded installed swipe, and activated it in language/settings but swipe keyboard doesn't come up.
