Hi Bill,
You are right it is similar to that problem with RadGlue, it was caused because we moved the mojoPortal.Business.WebHelpers.CacheHelper into the mojoPortal.Web project.
I've just uploaded Mobile Kit Pro 1.1 which should solve the problem.
Note that there are not any real changes to Mobile Kit Pro other than being re-compiled against the latest mojoPortal.
Can you download the new Mobile Kit Pro and confirm it solves the problem?
Thanks,
Joe
