Asset Store Picture Problems

Hi guys could someone give me some advice.

As the templates i downloaded from unity3d/will/ or something similar. Unity will not accept them and says that Pic is not true 1010x389 rgba png.
This is so annoying been trying lots of different things now for about 4 hours.

Please someone help


Sorted it thanks

In PhotoShop instead of saving it as a 32 bit PNG RGBA.

save it as a png in web and devices because in there it adds 8 bits to the current save and done!
