Vanilla Calendar problem installing

[Guest goce.nakov]

Guys

I have problem installing Vanilla calendar, I'm using Android Commander and first I'm deleting T-Mobile calendar and CalendarProvider apk's and odex files of them

After that I'm pushing Calendar.apk and CalendarProvider.apk from Shadows ROM, then I'm rebooting the phone but when is booted there is no Calendar in system applications,but when I browse system/app folder from RootExplorer I'm seeing Calendar and CalendarProvider.apk in it.

What I am doing wrong here?
