All Data and Processes Gone From Local Repository

I am currently a student using rapidminer for one of my classes and when I opened rapidminer to continue an assignment this morning all of the data and processes in my Local Repository are gone. The processes that I was recently working on still show up under recent when I try to open a process, but when I click on them it says that they no longer exist and when I look in the folders there is nothing there. I have already checked the folders on my computer where the data should be stored (as well as checking to see if they could be anywhere else) and I am not able to find anything. If anyone know of a way to solve this issue I would appreciate it, since all of the work that I have done this semester is now gone, and I need a lot of those processes for future assignments.
