Help I can't install S2E with Link2SD

[moustafaatchy]

I have CM 7.2 on my phone and I want to install:
-S2E to move dalvik cache to sd-ext
-Link2SD to move apps selectively

I had to install S2E first and Mount sd-ext as ext4 and reboot to get it to work
So I'm able to move any thing including dalvik cache
Then I install Link2sd and reboot.
After that I have 2 problems
1-S2E doesn't allow me to move anything except for dalvik cache (that is already moved)\
2-Every app I install can't be opened (gives me Force Close message) until I reboot each time I install them.

I tried to install a2ext following this guide but in Recovery it says "Installation Aborted (Status 0)" Can it be due to different CM7 version ??

One more question
By following this guide will I have to move dalvik cache manually each time I install a new app ?
