I just tested it here on my 7.01 backup and it's working fine.
You mean you haven't replaced the file? That's my entire method for unlocking the gallery. I included the save to make it easier for people to get there, but the map file
must be replaced for it to work.
My best guess as to what is happening is that you didn't download
my unlocker, but some other one somebody shared. Mine is the one on post
#4,983. Make sure to follow
all the steps correctly.
Also, check if this guy is here in your map. If he is, you're loaded into the wrong place, scenes should still work, but there's a bug (by the dev) when leaving the scene that leaves the map blank with just the standing picture showing up. Either use the save I provided or load into a new game and teleport into the gallery using the cheat menu.

And yes, you should update your game. Some people have posted updates here. Don't know which was the last one, but the game is currently in version 7.09. The unlocker should work regardless, but it doesn't hurt to update the game whenever there's a new version.
If all that still doesn't work, unless you're willing to upload your
entire www folder, all I can do tell you how to unlock it yourself. It's not exactly what I did, but it should work.
Sorry, I wish I could help you more, but there's simply not enough to go by. Like I said, a screenshot of the error and your current map file would help.
