If anyone is still reading this thread, I have tried to upload my package and I got the error that I used the wrong package (check file extension). I got it from the Application Data/Temp Packages folder and it was in my folder I created and there was a file titled SoundPackage.data. It was the only file I could find that was all in one state. Do I just use a .rar folder and upload all my individual sounds? I thought since the Sound Packager was a program, it would simply use a program file. But since I don't know what I'm doing, I might have the entire process all wrong. I also did a search for the error message I received and was unable to find any information about it.
Can someone point me in the right direction, please?
Ok, I tried to upload the .rar file of all the sounds just to get the error message exactly, this is what it said:
Your skin has failed to upload.
The skin file you are attempting to upload is not valid. Hint: Check the file extension.
When uploading a new skin, your Skin file must also be submitted.
