If it is indicator from the Market and if you bought it so you cam add it for MT4 directly from MT4 (you do not need any webpage for that).

Where can I see my purchases?

You do not need to open any website in case you want to install it.
It should be installed directlt from Metatrader (look at tghe links above about HowTo).
