Points failure

Sorry, I have no idea of italian or german, so i have to post in english.
My problem is that having my money positive, i was given (-) points, and it's a pretty shit because i would have made a lot of points.
The problem may be that o saturday morning i selled and buyed players, but both trasfers was made at the same time, I mean that both transfered appeared on the news page at the same hour.
I want my points back :/

Sorry, but your balance was negative on Saturday morning!
