Can't load save files uploaded to PSN Cloud?

I uploaded my save to PSN's Cloud storage because I knew I'd be at my family's place and playing on another PS3 for a few days. I made a lot of progress during that time. Now I'm back home and after downloading my save from the Cloud storage and overwriting my old file with it, I can't seem to load it. If I go to continue campaign, it still tries to load from the old save file, even though it's been OVERWRITTEN. Why is this happening and how can I fix it?

Alright. So I found a workaround. I had to delete my install data. How delightfully annoying.
