As far as I know, it's the only change. I've had PlanPlus before, though...just an upgrade today. Also, I get no error message...it just acts like it doesn't even recognize that a calendar is there.
I have reinstalled planplus, tried to reinstall the PocketInformant feature, but now it appears that even that is messed up. I get this: pocket informant synchronization interface tables not found. Thanks for your time and help. I'm not sure where I've gone wrong here. Nothing seems to be syncing correctly now, save the address book.
I don't use PI now, but I have used it in the past. Try checking their FAQ and tech support. Are PI and PlanPlus compatible with each other? Does PlanPlus install on your BlackBerry as well as on your PC? When I used it, it was a PC app and I was assuming it still was.
