Site completely gone and can't re-install wordpress!!!! please help!!!

Hi.

My site has the “Forbidden” page on it. So, when I went to try and login to see what’s wrong, I can’t because it still says “Forbidden” on it. Then, I went into my c-pannel and it says there are no files!! I installed a plugin the other day via the web (not the plugin thing in WordPress), so i’m not sure if that did this or what happened, but my site is just gone.

I tried to re-install using the QuickInstall in my hosting account but it didn’t let me install it.

I also tired researching and changing permissions and nothing is working. ??

Any help is greatly appreciated. Thank you!!

Update: I tried to reinstall wordpress using Core FTP and it says that a database with that name already exists, but I deleted the database and everything. Basically at this point, my site is just non-existent and not even responding to allow me to re-install nothing. I cannot do anything. I did contact my host about this issue. But in the meantime, if anyone has any suggestions, please let me know! Thank you. ??
