My apologies for the delayed response.
There were multiple tickets merged in this month’s release of ARC 1.0.4 that will hopefully prevent any corruption from seeping into downloaded local content.
However, checking through automated diagnostics from your account since your report, tech support has been unable to ascertain whether or not you’re experiencing stable playback. We’re standing by to assist in the event that you’re having problems with ARC.
Thank you for your patience.
