I deleted the powergallery from online, did a fresh download and reinstall; went through the wizard ok. On the last page it said I had already set up the username and password. I did recognize the username but the password was only 10 spaces; not what I thought was correct.
I now have a gallery online and logged out. I tried to log in again to the admin to no avail. If I do another download and reinstall, is that going to mess up the gallery I already have? Can I just reinstall without deleting the other files online? Brain dead at this point and tired.
