Well, I just couldn't wait after all !!
And went and bought the download from the TriSynergy site !!
As I downloaded it, Norton deleted all the files under the threat message "WS.Reputation.1"
I tried again but the same thing happened.
So I got Norton on the phone and as I assured them the files were safe, they agreed to help me get past the problem.
When I went to download the game again Plimus told me I wasn't allowed to !!
I've sent a brief email to TriSynergy (as instructed) hoping for a reply from someone who will help me get this sorted.
I do have all my receipts and the Serial No. etc..
Mad .... Who isn't actually feeling very cheery
