Glad to help you get some clarity mowgs to max. Another idea is to hop into the Telegram and ask for some guidance on there.

Ask if any admins are around and tell them you're new to crypto, that you bought POWR over at Bittrex and wanted to send to MEW, but used the contract address found on ethplorer.io

They may halp fast track a resolution.

Ok just in case you didnt know heres a few more tips...

1. When logging into myetherwallet, never Google myetherwallet beforehand. There are multiple clone/phishing websites that look almost identical to myetherwallet.com Also, scammers use google adwords and bots to rank higher for a search response. So even though its at the top of the list it doesn't mean you're going to the website you want to.

2. Try make a word document that is filled with url addresses of the exchanges you use. Copy from that list of your exchanges into your browser directly.

3. If you're looking for the url of an exchange, use a direct link from an admin pinned msg in Telegram. Alternatively, go to coinmarketcap.com, look for whichever token it is, click on 'markets' and find the exchange url. Copy and paste that in your word document.

Thats some of the stuff I do
