What do you mean when you say you "deleted" it. How?
Also, are you absolutely sure? Some things have changed since older softroots. Long-click (press and hold) on one of the icons and see if anything happens. If some little icons appear, you're still using the mynook.ru launcher; click on the "+" to add apps to the menu, and click on the "x" when you're done.
If nothing else works, there's always the nuclear option:

If this works and you can get adb going, installing apps is done from the command-line like this:
./adb install packagename.apk
Good luck!
