Help - Tried to Fix Crash When Adding Pages but This Happened

I truly have no idea what I did. I was having a problem with indesign crashing everytime I tried to add a page to my spread, so I saved it as IDML. I forgot to rename it, but when I opened it, this happened and it is on the entire pasteboard/every page in the file. Please help, freaking out a bit! I am a self taught Indd. user, but this is for my job. Thanks!
