WPMU Database Reset Plugin Erased Site

I am currently a part of a group and we were using a site called ourmakerlife.com on WP. We were using the Lino theme by Pankogut. The group decided to go with Weebly (they now use .org). Personally, I like WP and found the Lino theme to be really cool so, I decided to create my own site. Well, I was gonna use the WP (ourmakerlife.com) to play around on with the Lino theme so when I set my own up I know what I’m doing.

I wanted a fresh start and came across WPMU Database Reset Plugin. After I reset the database, it erased the site. Ourmakerlife.com no longer exist now. I can’t log in as an admin anymore. The themes section now shows blank tiles. I cannot install any themes. I cannot install any plugins either. Basically, I cannot do anything after using this plugin. I made a HUGE mistake clearly. I was supposed to use WordPress Database Reset Plugin by Chris Berthe and not the WPMU one by Hassan.

If the possible fix requires editing something in the FTP, well, again, I am part of a group and the person who installed the theme and set everything up doesn’t live in the same state as me. I don’t know what host site they use if they went with FTP.
