VNX53000 Installation Assisstant problem

Hi,

I am new user of vnx5300. I started VNX Installation Assistant to install new vnx5300. After successfull health check I got pre-configuration screen, clicked next, and after that application froze. I was too impatient probably and closed Installation Assistant too soon thinking that something is wrong.

Now when I try to start Installation Assistant again, I see profile I tried to initialize in my previous step with status "In progress". It stays like this for more than an hour. Is it normal, should I wait longer, or should I delete this profile and start new configuration?

Thank you for your advice and help!
