This has now been resolved, thank you both to Lightlord and Zodiac. Appreciate the advice from everyone.

Still no replies to my support request on the site or my message to Lightlord. Can't message Zodiac because I'm new but I did email him.

From what I can tell I am only missing the last character of the secret URL. I tried all possible ASCII values to no avail. Does anyone have any other ideas?

Or does anyone know someone at the site they can ping? I don't mind waiting if I know someone is at least looking at it. But it sucks to be completely ignored.

I've played there a number of times without issue. Two weeks ago I made a successful deposit of .049 BTC into a new account. Unfortunately I copied the secret URL incorrectly (truncated it by a character) and can't access the account. I contacted support through the site and haven't received a response. I also contacted Lightlord via message here and haven't received a response.

I know the site isn't a scam (and people are busy) but this is ridiculous...

UPDATE: Now resolved, thank you 777coin and others.
