Default Euler-Model with Phase Accretion

Marbau is on a distinguished road
I am running a simulation using the Euler-Euler-Model. I want to simulate the accretion of a film of water on a surface. As I use Fluent 14.0, I have to use the UDF provided by Ansys in the context of a tutorial.
So far it runs pretty well. But if i stop the simulation to make a check, I have problems when continuing with the latest case and data files. It still executes the Wall-Film-steps during the calculation, but there is no phase accretion anymore, viz. my wall film stays in its last saved state.
I tried to rebuild and reload the UDf. I also checked the boundary settings, everything looks OK.
Does anybody have an idea why this happens?
