Hi, I just installed adzone and followed the documentation. I am running django 1.7 on a python 3.4 virtualenv. I added adzone tomy installed apps and get the following error when starting the development server:

File "/home/xzased/.virtualenvs/app/lib/python3.4/site-packages/django/apps/registry.py", line 131, in check_models_ready raise AppRegistryNotReady("Models aren't loaded yet.")
