Don't delete your account, this won't change anything. I
don't quite understand what is causing this, I don't have
enough information to detect where the problem is,
unfortunately. I think you must do a certain action that
causes that, because I have never encountered this problem
with my profile and it seems difficult to reproduce the
problem. For now, just make copy/paste like shebawolf said,
and tell me if you get any clue of why or when it occurs.

Well I don't know how the actual problem can be sorted. BUT
I can give you some information copy-paste your Profile into
Microsoft word and save it in your computer. At least you
wont completely lose your profile text and have to re-do it
if you do this.
Hope this has been helpful.
