Aurora settings -> misc -> Use preview versions. Then restart Aurora and update to 1.2.0. After you logged in, press Ctrl+Alt+Shift+D. Aurora will now hang for a few seconds and a Aurora_debug.dat file is generated on your desktop. Zip this file and attach it here.
if its ok to ask...is basicly choosing to just always use the preview versions of Aurora basicly the best choice to make for the future for any and such moments as this one should they ever happen in any kind of way? i ask cause if so ill switch myself in case im ever in need so ill be able to provide all the info i can right when asked =)
