I get the error " 1. You have installed a Jcow! in the selected database, please choose another database" but was told that the upgrade would just overwrite the previous files, saving the posts already made.

Now my site is totally inaccessible. [url]http://www.strengthscene.com[/url]

Please help because my site is dead now!

You should upgrade, not install. Please contact support via email, they can help you on this.

Thanks for the advice. I'm communicating with them through email now. I'm impressed with their commitment to customer satisfaction. :-)
