Can't login

[czar2178]

I have installed and uploaded some pics on my gallary.  It has been about 1 week now and i am trying to go into the admin login, but evertime I try loging in it accepts it but takes me right back to login and nothing else.  I can click on forgot password and it will reset it after the entire process, but after a couple of days the same thing happens and I have to do the process all over.  Please someone help, I need to give some people access to the site but nothing, they can't log-in it keeps going back to login. 
site:

Are you using CPG with PostNuke?

sorry, I am very very new to this and I don't know what you mean.  How do I find out?  This is a important project for my family so that members overseas can view pics of their family.  This is all charity work from me to them.
