Has anybody else also encountered non-payments of points after completing a task?

I've already completed two 17-points tasks: (Évaluation des résultats de recherche sur www.pagesdor.be (R)), but my points never went up at all...
Also the % of accuracy never went up after completing these tasks...

Anyone else encountered such problems???

EDIT: the finished tasks are also not listed under "completed tasks" :s WTF is going on
