I keep receiving this error message when I try to access my contacts. Ironically, it works fine if I unmount my SD Card but as soon as I mount the SD Card, I get the error message even if I didn't even have my contacts open. I've taken out the battery and that didn't seem to do anything. I have a lot of apps and pictures on my SD Card because I kept getting the "low on space" message so I need the SD Card mounted. Is there a way to fix this?
