I click on osu! and get this;
System.InvalidOperationException: Failed to compare two elements in the array. ---> System.NullReferenceException: Object reference not set to an instance of an object.I tried running it in different compatibilities and as administrator. I have the .NET stuff, and I tried uninstalling and reinstalling everything... What do I do? I just wanna play osu! Wah!
