Hello @Owenmarc2013, Welcome to the community forum and thanks for posting.
I'm sorry to hear it says "there's a problem" when you try to sell your Crypto. It sounds like your account may have a temporary limitation in place. Account limitations are placed in situations where we see unusual or suspicious activity, or when we need to collect information necessary for keeping your account open. When we place a limitation, an email is sent to explain the reason for the limitation and what needs to be done to resolve the problem. In most cases, you can find options to resolve the limitation in the Resolution Center.
I hope this helps,
- Sean
