Several weeks ago side loading was working on my windows phone 8 device. I had installed a valid enrollment token (.aetx file). I was able to successfully side load signed .xap files (either via downloading in IE or attaching to an e-mail). All was good.
Then I ran down the battery and left the device for dead for over a week. When I tried to run the old side loaded apps they worked. But when I tried to side load a new xap I got an error message that said something about it having been too long since the enrollment token was verified with Microsoft. I wish I'd written it down, because I can't get the error to show up again.
Now when I try to side load apps nothing happens at all. It pops up the familiar dialog that confirms I want to install the app ("Would you like to install [my app] from [company name]?"), then I click install and the dialog disappears and the app isn't installed.
When I try to install the .aetx again it pops up the dialog to install, I click install, and then nothing (same as the first time). Xap files still won't install.
Guessing that the phone needs to re-verify the enrollment token with Microsoft I tried waiting 24 hours, but that didn't help. I'm running out of ideas.
In lieu of a direct answer, could someone help me at least get an error message? Nothing shows up in the output window in Visual Studio when I try to side load while debugging an app and I'm not able to find any OS level error logs.
