DataField - Not visible anymore since Edge 520 FW update

I made myself a custom DataField a couple of months ago, I sideloaded it and worked nicely until recently.
I think it dissapeared when I went from v6.20 to v7.0, thats the version when Apps and Widgets was introduced to Edge Series.
Tested to Sideload it again but it wont show in the Connect IQ menu when I try to attach it to a page.

Is there some major changes made that makes this or what should I do to make it visible again?
Is there another folder on the device I should use? I put my x.prg file in /GARMIN/APPS as usual.

I´m still on the 1.x SDK, will try to update to 2.x, but what I´we read, DataFields created for 1.x should work nicely on devices with ConnectIQ 2.x

Help Please!
