The reason I'm wondering if I may have been hacked is because I received a "notice" from my host company a few days ago telling me that my email had been hacked, and one of the addresses was my sales@yarniapdx.com email address that I believe is the one associated with all my OpenCart actions.
How can I get some help with this? Is there a central administrator who I can prove my identity to, so they can unlock my account for me? My actual storefront still seems to be up and running, but I can't access anything in my back office!

Any help or advice would be appreciated.
Thanks,
