I posted this a few steps back but I'll make a step by step here anyway for people getting the scan lag:
1. Clean uninstall .NET FW with

.
2. Reinstall .NET FW latest version from microsofts website (google it)
3. close vent/steam/mumble/xfire/fraps/macro programs
4. add hack to your AV exclusion list
5. restart PC and run the game from the launcher normally (no scripts / batch files / arguments / etc)
6. put the game into windowed mode just to test the hack (Admin), it might take a few seconds the first time to scan and find it but after that you should be solid.
Hope this helps, you don't have to use windowed mode but I just use that for testing the first time around. Although I did all of the above I the trick that finally fixed it for me was launching without the steam overlay and using the launcher normally instead of bypassing it via shortcut arguments. Now I still do run steam and mumble however with no overlays, the reason I mention step 3 is to remove those from the equation (trouble shooting). Note that it was working despite the lag and pausing and searching all the time, it just took like 15 seconds to respond to anything I did. And, as always, great hack!
