Translating on yosemite

Hy,

I’ve been trying to update the Hungarian translation of TotalFinder on Yosemite.

After running dev.sh, TotalFinder refuses to start. When I start it from a terminal, it logs the following:
/Applications/TotalFinder.app/Contents/MacOS/TotalFinder
2014-11-26 20:21:28.410 TotalFinder[44209:3153072] agent v1.6.17 started (TotalFinder)
2014-11-26 20:21:30.433 TotalFinder[44209:3153072] requesting injection into com.apple.finder[44197]
2014-11-26 20:21:30.988 TotalFinder[44209:3153072] TotalFinder files have been modified since installation (the shell is corrupted)

Please help me how to get started!
