Probably, that was due to a syntax change from previous Regex Engine introduced with NT 5.0.
The What's-new-file for v.5.0 explained:
"There are significant differences compared to the previous regex syntax used in earlier versions of NoteTab. (...) \n for newline (hex 0A); before it was hex 0D 0A. Replace \n with \r\n."
One should thoroughly note the meaning of '\R' which was introduced with NT 5.5:
"Updated the regular expressions engine to the latest release, which is based on PCRE 7.4. The \R newline sequence now matches either CRNL, or a lone CR, or a lone LF."
Furthermore, it doesn't work in Character Classes and in substring replacements.
