As a member of an LLC- only 10% if the LLC is in debt and cannot pay am I personally liable?

You shouldn't be personally liable, unless you personally signed any of the debts or the LLC was a sham and not a legitimate business.

The manager may have liability to you and the other members, depending on his actions. It's possible you may be able to recover some of your losses, however, it would take an attorney's review of the matter to determine if you have a potential case.
