Upgrade failing, installer can't log into the Mysql Database

[Arsenal101]

I am trying to help upgrade a fog installation to 1.5.10 to be honest I am not sure what the old version was. The installed gets to the point where it asks to login into the mysql database and wants the root user password. I enter the root user password and it won’t accept anything I enter.
I know I can log into the DB with it because I can successfully mysql -u root -p and enter the appropriate password and it works just fine. but for some reason the installer doesn’t like it.

Any ideas?
