Manually resetting theme of BlogEngine.Net

I was experimenting with themes that are provided with BlogEngine.Net. I liked how Fresh looked. So i decided to use it. So I hit apply and all is well and good. Now I wanted to add a blog entry. I could not find Login link on the page anywhere. And now I had noway to reset the theme that has login button. So i looked around and found the table be_Settings. There is a column in there with name SettingName which has names of all the settings and their corresponding values. There is a row with Theme setting name. Here you can alter the value of this setting to whatever theme you want. Obviously you have to have that theme on your server :-)
