CAN'T SAVE WITH RESOURCE HACKER.

As the title states, I am having a problem saving my RPG_RT file using resource hacker. I've experienced this on both Vista and Windows 7. I'm trying to change my EXFONT at the moment, but I can't save it at all. I get this error all the time:



I'm using a 16 color bitmap, I don't know if that's a problem. I've gotten the error trying to edit the status screen dialogue in the past as well.

Writing to the rpg2003 folder alleviated the saving problem, although now when I replace the RPG_RT with the patched one it claims that it isn't a valid Win32 application.

EDIT: Apparently the project I was testing it out with had a bugged RPG_RT or something/ It works fine everywhere else. Thanks for your help though!
