installing

I am having a bit of trouble reinstalling WP in my root folder. I have deleted the original blog because I was having a problem with it that I couldn’t solve- posts were not showing up. I removed it via fantastico on my web host. The install page says that there is no currant installation, but it won’t let me install a new one. When I try it says:

“The installation can not be completed:

– You cannot install more than one script in the root directory of a domain.”
The root folder is empty. Will this resolve itself given time or is there something else I should do?
