SImulator Client Bug Report

I sign-into my Premium Account, and use the SIMULATE green button to get the best 7.2 path for my Aritfact Weapon. I get the message, “The specified simulation could take a long time to run.Please start or download the client program to run it on your own computer.” I DID that a MONTH ago !!. So I go to the folder on my computer and run amr.exe, and get the message, “The client program is already running…”

So now I am stuck. The server will not connect to my already running client.

Try deleting the client and all the files, then re-download it and run it.

I am having the same problem. I am new to this please help
