Can't understand a darn word? Don't be surprised. Estonian is completely unrelated to Russian, Latvian, Swedish, German or any other Indo-European tongue. Along with Finnish and Hungarian, Estonian belongs to the Finno-Ugric group of languages, thought to have originated somewhere beyond the Urals thousands of years ago. Luckily, the younger generation and those in the tourist industry understand the value of the international language, so you should have little trouble getting around in English.
