And it was working and compiling without a problem a few days. However, today when I needed to make a correction and uploaded it again, it showed this:

Can someone explain me what is happening? Apparently, something is using more than the designated 64K on a .DEX file, but I dont have any idea of what that means, or what is a DEX file. Thanks for your help
