XCODE fail to load platform

Question

I am trying to learn iphone programming and I have just upgraded xcode to version 3.2.4 (and to iOS 4.1).

When I create a new project I get the "Internal error" seen below. What is wrong? (by the way, I can't see any message in the console)

Internal Error

File:   /SourceCache/DevToolsBase/DevToolsBase-1705/pbxcore/Target.subproj/PBXTarget.m
Line:   1603
Object: <PBXNativeTarget:0x20088e7c0>
Method: createPropertyExpansionContextWithBuildState:

Platform failed to completely load.  Examine Console Log for error messages.

The same happened to me, and I fixed in the same way. Reinstaling from the same dowload image.
