What's wrong with the textures(already installed 10G sourcemedia)?

[JonnyFiveAlive]

So my texture pack is working fine.. However, when I save my map and come back later. I try painting agian, The editor paints [tex not found] onto my map. Even thoughI can paint using those "not found textures".

Anyone know how to fix this bug or a work around for it?. I find if I make a new session and copy my locations folder into the new session, it then works agian. But that's alot of work to create save, quit copy paste, relaunch everytime the ediotr crashes or i save and exit....

please help,
thanks,
