Hi! I have a question but first Im gonna tell you my situation. So here,
I received a token long before it was listed in an exchange. Few months later I checked the token on Myetherwallet (MEW) and it said that the contract address was changed or has been updated.
Does it mean that I cannot use those tokens with the previous contract address?
Have you checked the latest news from developers? if they have changed the contract address and you should get the new token and if you didn't and then you must try to ask the developer of your token about this problem. If that was a token swap and then try to ask do you can swap your old token into the new one or not.
