Hmm.. unfortunately I don't think I can much help as I've never seen
that error
I generally go:
cat myttc_2008-12-21.sql | mysql -uroot -p ttcdata
google searching 'mysql error 126' seems to return various mysql
settings fixes, perhaps one of those help?
I suggest dropping the database and trying it again from a blank DB
when i create my database I don't set it to utf8 or anything - I just
leave it to whatever it decides:
CREATE DATABASE ttcdata;
is all that I run, i'm not even sure what the defaults are actually.
Let me know how it goes, I'm curious what the problem is
