I get a strange error with the "vignette" photo app and I'm looking for a fix

[DaygosDankest]

Hey, recently this app has been unable to save pictures. It will go through the whole process of "processing" the photo but then I get n error that says "an error occurred while processing your photo, is your sd card not instered or unmounted" or something to that effect.

Anyway, has anyone encountered this before, or does anyone have any thoughts on what the problem could be?
