The path in the inner exception looks correct: \"Content\\Round.xnb\", the extra slashes are just because it’s escaped. This is a relative path from your executable, be default it’s something like: Visual Studio Projects\MyCoolGame\MyCoolGame\bin\x86\Debug\Content\Round.xnb. You should be comparing this path to the the real path to the Round.xnb file, not the png.

• If Round.xnb does not exist anywhere, then your png file isn’t part of Content project, or the Content project isn’t being built
• If the file does exist, but is in a subdirectory, specify the name of the subdirectory when you load the texture like: Content.Load<Texture2D>("myDir\\Round");

Since the inner exception isn’t looking for “Round.png.xnb”, you have your names up correctly and @Ricket’s answer won’t help you any further.
