Hello, I just downloaded the trial version of Lightroom 4.

So far I found 3 big problems, the MAP & BOOK modules are not loading at all: An error has occurred while trying to load the module (I have the messages in French, I try to translate them as good as possible)

Once I clic on MAP, I can't use Lightroom anymore.

And an even bigger problem, I CAN'T export anything, I have the following message : an internal error has occurred, Assertion Failed

I tried with a new library, I deleted old preferences, I even re-installed the trial version, nothing changed...

I have Mac OSX 10.7.3

Problem fixed. I had to clean all older lightroom folders everywhere. Sureley a bad plug in.

Working fine right now.

Could you be more specific about what you cleaned out?o I’m having the same problem and have been through all my “User Preset” folders in the Library/Applications Assistants/Lightroom folders and they are all empty.
