Hi OGHuxtable, looks like the problem has been solved.
I checked the skylanders list on the game and Star Strike appeared as "FREE" so I just got it again. Only remaining problem is that it has been reset to starting level but that's no big issue to me.
Hope this helps in solving other players' problem.
