Sorry to hear you are having difficulties with your ARCbot. There are several ways you can contact a support member for help.
For assistance via the forum, create a new thread under the support section of this forum. (here)
If you come to the chat room and no staff members are online, post a question in the forum and maybe another user will be able to assist you. Creating a support ticket is also the fastest way of connecting with a staff member when none are online. (It may take a few hours for a response via support ticket)
