Windows offline version fails to compile sketch

[soxfox42]

When compiling any sketch on the Windows version of ProjectABE, I get this error:
SyntaxError: Invalid regular expression: /C:\\Users\\<Username>\\AppData\\Local\\ProjectABE\\User Data\\Default\\store\\build_YV99vY\sketch\(.*)/:
It looks like the path separator at the end is not being properly escaped.
