Album app problem

[meher29]

My album app has suddenly stopped working. Whenever I try to access it, a message saying "Memory Unavailable: Memory unmounted or unavailable. Mount memory to continue.", shows up. I do have a SD and I can view my pictures in other apps like Google+ Photos but my Album app isn't viewing any. Please help.
