Mac OSX. sqlite attempt to write a readonly database smartsvn

I recently have installed SmartSVN on my OS X. But I tried to do an UPDATE from a repository and got this error:

Working copy '/Applications/MAMP/htdocs/logiciel_net_profil' locked. '/Applications/MAMP/htdocs/logiciel_net_profil' is already locked

And when I do a cleanUp this error is showed :

sqlite[S8]: attempt to write a readonly database Additional errors: sqlite[S8]: attempt to write a readonly database

Need a help
