A previously functional Link module has suddenly started giving this error:

Error: Links is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: Count cannot be less than zero. Parameter name: count ---> System.ArgumentOutOfRangeException: Count cannot be less than zero. Parameter name: count at System.String.RemoveInternal(Int32 startIndex, Int32 count) at System.String.Remove(Int32 startIndex, Int32 count) at DotNetNuke.Modules.Links.LinkController.GetTargetContent(String Url) at DotNetNuke.Modules.Links.LinkController.RefreshLinkContent(LinkInfo objLink) at DotNetNuke.Modules.Links.Links.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

There were several links entered (and functioning) then suddenly this error appeared.   No new extensions have been added to the site since  this message appeared.

This is a DNN 07.03.04 (45) portal and Links module is version 6.2.1

Any idea what's going on?

Thanks,

Thanks.   I did an upgrade on the module (even though there was no indication in the list that one was needed) and that seems to have fixed things.  

I appreciate your response.
