Can't FTP to or Upload my Website

I was attempting to upload my website (from GrendelHosting - transferring hosts) when my FTP client was suddenly unable to connect. Then, the CPanel also stopped working. Is there anything wrong that I am doing? Did I exceed the file/directory count limitation (inode)?

It sounds like one of the files tripped the abuse detection system and your account was suspended. Can you please send an e-mail to [email protected] with your username so they can check it?

I’ve sent the e-mail.
