Market Download Issue

I have an issue about downloading/Updating content in the Market after the Nether update was released. When I want to Update/Download content it shows that I dont have enough space while I have enough space. Even if I delete for more space it will say the exact same MB requierd as when I tried before, and when I try it again the amount will stack if im still on the same tab.

 

I dont know if its general or just me, but pls fix it asap
