yeah, this is...
everything's set to read-only. i've been through this before and know it's an access thing, but it's...i think it's connected to reinstalling. windows is confused because it thinks the previous install owns the drive. and, even when i take ownership and delete the old user and all of these other fun things there's still remnants in the directory structure that are getting in the way. this is all over the internet, and nobody has a good answer.
i'm going to format the drive....that'll wipe out the partition table, which i think is the crux of it. an ntfs error. when i have the project in ram, it's running properly; it's when i save it to disk that it gets corrupted.
