Users were encouraged to archive their photoshop.com accounts during the transition period (Feb-Aug 2013) from photoshop.com to revel. Unfortunately, the transition period ended in August and the files were deleted.
If you allowed it, then your jpg files should have migrated to Revel. For migrated accounts, the adobeid and password are the same as they were for Photoshop.com. Didyou allow your account to migrate? Have you gone to adoberevel.com or downloaded the revel app and logged in there?
