Invalid username/password

Hi,

I've tried to install NetFlow Analyzer standalone applications to try it out, but after installation I keep getting invalid username/password although it's new installation.

Previously I installed OpManager, didn't have a problem, I uninstalled it and installed NetFlow Analyzer but keep getting invalid username/password. I've restarted the service it's the same.

I've tried to uninstall it and install it back again but it's the same.

I've found somewhere to check startDB.bat, but it says database already started.

Can you help me to get into the program and check how it looks?
