Robots.txt 404 problem

[SamCUK]

I've just set up a wordpress site with a hosting company who only allow you to install your wordpress site in http://www.myurl.com/folder as opposed to the root folder. I now have the problem that the robots.txt file only works in http://www.myurl./com/folder/robots.txt

Of course google is looking for it at http://www.myurl.com/robots.txt and returning a 404 error. How can I get around this? Is there a way to tell google in webmaster tools to use a different path to locate it? I'm stumped?

Can you do anything at all at the root of your domain..ie myurl.com ? This makes no sense. How can you host a domain and have no control over the root of your own domain name..the one you hosted. Don't you have FTP access ? When you connect using ftp, can't you see the server path for the root folder ? You should. I would check via FTP. I have never seen such a scenario.

Can you give us the name of the hosting company by chance?
