I am trying to submit a Windows Phone 8.0 xap file to the store. It uploads, after the upload it says "Analyzing package", then "An unexpected error occurred. Please try again later. If the problem continues, contact support."
I contacted Microsoft, they told me to clear the cache, history, etc. and try again. I emptied my browsers and restarted, but it didn't work. And I guess the problem is not really about the browsers, because they are able to upload the xap files but they don't get accepted by Microsoft's system.
I also tried an old xap file which was accepted by Microsoft before. I stil get the same error, so that's probably not about my packages.
