Error : Bitmap color context is not valid

Hi,
I'm french so excuse me for the bad english.
I read a lot of good things on your software so i download and install the trial version to try it.
The installation work well but i have this error when i open image at the end of the tone maping : Bitmap color context is not valid ("Contexte de couleur de bitmap non valide" in french).
It seems to be a .net error so i try to install / delete /install .net4 but it steel doesn't work.
I'm on windows 7 64-bit, with 4GB of ram and a intel i5.
Could you make something for this ?!
Thank,
Guillaume.
