Anything at all? I just tried reinstalling tf2 with now luck, still wont save.

Hiya, I'm trying to make some smooths and they simply wont save. I've heard of other poeple with this issue and was wondering if it's still persisting for others? I know for sure I'm doing everything correctly, I hit "ok" and my smooth window just closes, 0 delay, and doesnt save. I've tried hitting "save" before hand with still no luck.

I've tried renaming the demo to a shorter name, downloading other demos, deleting my old tf folder from before steam pipe, nothing works. I'm running on Win7, dont know what else may help.
