I've changed the subject of this thread. Please try to use a descriptive subject in the future, rather than just "archicad help", "help please", etc.

Give us more information. We can guess that you are on Windows, because of the 'not responding' message. The Frank Lloyd Wright house tells us that you are on 11.
What build were you running -had you updated to the most current build (1210) and the most recent library?
In which version of AC was the file created? The objects from an earlier version will likely not all appear with just the 11 library. Instead, you need to save a PLA from the older version and open that in 11...and then fine-tune the library transition. (Or use subset libraries.)
Freezing at the splash screen, which is right when the WIBU key is checked, suggests a possible problem with your USB key. Have you unplugged the key to see if you get further - to the point where you are told you are entering Demo mode?
