Does anybody know what is this...?

I just upload a new version of my app.

I have the new Maverick.

At the end of application loader, I got this…

– WARNING ITMS-9000 "Missing recommended icon file…152x152 in png… at

SoftwareAssets/SoftareAsset(MZItmspSoftwareAssetPackage)

I see the file in my folder…a .png file with 152 px by 152 px

Does anyone knows what is that, and how to fix it?

I have 3 warnings (file 120x120, file 76x76 and file 152x152)

but I do have those 3 files in my main folder…

any ideas

Thanks
