xcubic.m+bhwguys works, although i had the same problem, but that was because i copy and pasted it like this:
xcubic.m+bhwguys.
the full stop at the end fudges it all up, without the full stop at the end the email worked.
And that problem with saving texts happened once to me, the culprit was a square (special character). It randomly turned up in my .txt file, delete any strange phenomenah like that and the saving to txt problem is solved.
