Thanks, edited the InvalidStrings.xml and works like a charm now.
Btw: I don't know if anyone else crashes with your files, since i'm the only one so far, who got a complaint. I checked your InvalidStrings.xml and compared it with the original one and the red line is missing. Maybe this is the cause of the crash? (Did not test it though).
Code:
<allm>
<Locale>
<Nation value="english"/>
<!-- 수정해야 하는 부분 -->
<ExclusionStrings value="€"/>
