Shadowplay won't record to Shield. Says low disk space.

New Shield with a 32GB micro SD card. Tried recording in the last couple days (using the built in shadowplay screen record feature) and it worked fine. I deleted those recordings to free up more space. Today it doesn't want to record, says low disk space. Bullshit. Just about the entire SD card is free and half the internal storage is. Anyway it shouldn't be a problem because I deleted the previous recordings.
