Hi. What permission and which indicator? Show us a screenshot of the issue so we can understand better.
To post a screenshot please see this: How to post a screenshot/indicator on Forex Station.
As for the indicator, don't rename it. Just download it, leave it with it's original name (as it is) and it will work.
Thanks for the screenshot. No, it's most likely due to a renaming issue from the old site - not your fault. Can you please attach the indicator to your message so we can look at it?
