HELP! Overwritten index.html

I tried installing a flash music player onto my blog and after I tried it and it didn’t work I deleted the files for the player from my server. What I didn’t realize is the player had it’s own index.html file and it overwritten mine for my blog’s index file. Now I don’t have a index.html and was wondering how I can get it replaced. I’m not good with coding at all from scratch so I can’t build it back. But I’m currently using the index.php but it isn’t displaying my previous post.

Anyone have a solution for me?

Thanks in advance.
