Certain apps wont install

Ever since switching to cm6 final, some applications simply won't install. I have install apps on "automatic" but I keep getting the error message, "error,can't install". The following apps can't install:
Google Skymap
Angry Birds Lite
Labryinth Lite
Paper Toss
Toss it
App 2 Sd

I'm sure there more but so far,that all I found.I tried switching applications download to internal and external, but nothing. Any suggestions?

I really wanted Angry Birds Lite game but it won't download :(

I believe because it automatically installs to the sd card, I believe that prevents it from installing properly on cm6
