It's better to use the Copy button at the bottom of the crash, then paste the crash message in a spoiler, than to take a screenshot. Much easier to get data out of text than out of a picture of words.
The crash happened because the variable v_rel_melody_firsttime is not defined. It's defined in week 7, when she lost her virginity.
The best way to fix this is to open the console and set the variable to True. Enable the console with UnRen.
I'm assuming there was a bugfix release that added the definition of this variable, and you played the version without the fix. Otherwise the variable would be defined when you hit week 7.
Jeff Steel please pass this on to the programmer. Variables that are added to a file after a release MUST be defined with the "default" keyword. Otherwise, people who have saves after the definition won't have the variables defined.
