font error

I use Web version of Photoshop,
I've uploaded Korean font (galmuri) and used it.
deleted the original font on my Mac.
and when I opened the PSD file again, there were a notice says that font file is missing.
I put back font and returned to the files, but still my font is not working.
What is strange is that I can still use the font on the new PSD file but cannot on the original PSD file I was using or the duplicated version of it.

Is there anyway to delete the uploaded font files, and reinstall it?
