Hi, I am running NF2 on steam and I want to change my fleet tag. I have a .png image located in my C:\Program Files\Steam\steamapps\common\Navy Field 2  Conqueror of the Ocean\Register folder named NewFleetMark.png and it is 32x32px in size with 1.57kb. When I click the Mark Change button it says that the image must be 32x32 and under 5kb as a 24 or 32 png file which it is.

Any ideas on what is wrong?
