We currently run our Ark server via Survival Servers. We use the Ark API with the latest ArkShop Plugin and have had no problems at all. The main thing is, Survival Servers, once you rent a server, allows you to FTP to your server - I used to use this for verifying mod dates, backing up server files to my local machine, etc. But I uploaded (following the directions) the ArkAPI successfully to the Win64 folder, created the necessary subfolders, installed Ark Shop, etc. Been running great ever since. They're also pretty reasonably priced, I think we pay $43 every 3 months for a 10 user Ark server.
