Sbuilder background image "Could not find the following map"

[RKE]

I've looked through the help file, I've Googled it, and I've even considered learning russian to be able to read the one thread that has the same error message.

All of the sudden, Sbuilder is throwing "Could not find the following map" at me, whenever I try to load up a background image.

I get the square box where the background image should be, but nothing shows up. I've tried loading up some old projects where I used a background image, and they work just fine
