on my steam account, when I go to the invertory, a sign almost constantly lights up that says:

Sorry! An error occurred while processing your request: You have made too many requests recently. Please wait and try again later.

although I don't log in to the invertory that often. when this sign disappears (once every 7-8 days) then only after logging in to the invertory once does this sign appear again for the same time. what is the reason? help me with this. thanks
