Cannot log in

[محروم.كوم]

Hello,
I have a v4.2 forum in my root directory and have just installed a v5 into a /area51 folder where I am going to restrict access to only a handful of people in order to stay within the lisence agreement (we'll be testing v5 before upgrading the main board which is the v4.2).

However, I cannot log into the v5 forum and was thinking that it may be due to the cookie settings. I've worked with phpBB for years, but this is the first day I've worked with vB. Could somebody please explain to me how the cookie settings should be and how to change them (via phpMyAdmin?) so I can log in?
