xcode encountered an internal logic error

I have just installed xcode 4 on my MacMini. I am new to developing and just today have started learning objective c. when i open xcode 4 it gives me an error:

Internal Error

Xcode encountered an internal logic error. Choose "Continue" to continue running Xcode in an inconsistent state. Choose "Crash" to halt Xcode and file a bug with Crash Reporter. Choosing "Crash" will result in the loss of all unsaved data.

and also when i click on the show details button it gives me this:

Sorry to ask something obvious, but have you cleared out all the previous XCode data before installing 4? Most of the previous problems came from carry-overs from previous XCode installations.

Dec 9, 2011 11:04 PM in response to Tim Fall

I typed the following commands in the terminal as Andreas suggested :

sudo tmutil disablelocal

sudo /Developer/Library/uninstall-devtools --mode=all

sudo /Developer-3.2.2/Library/uninstall-devtools --mode=all

sudo tmutil enablelocal

Then I deleted the folders "Developer" and "Developer-3.2.2".

Is there something else to delete?

I'll give it another try.

Thanks for your help!

EDIT : actually, the second comman didn't work as I don't have a developer-3.2.2 file.

Were you reinstalling XCode 4 before you ran it? It might be worth trying something like CleanApp to make sure everything is gone before reinstalling.
