access to providers links

I have premium access however I frequently receive the following message when trying to access providers links?? I don't understand. I'm not trying to post or edit someone else's post, access administrative features or some other privileged system.

XXXXXXXX, you do not have permission to access this page. This could be due to one of several reasons:
Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

Send me the links you are attempting to access and I will look into it.
