Try backing away from Karim first, then enter the spot you're supposed to jump and press the 'confirm'/'action' key while facing up. See if that helps any?
There is a known issue with one of the quests that can take away your ability to jump down the tower. If you were able to jump down the entire tower first, then it shouldn't have created an issue *only* with jumping back up though.
If nothing else works, you might want to try sending Indinera a PM and see if he can look at your save file and help you out. If this is a bug, it's a new one.
