How to find and transfer my coins I purchased in the beginning

Hi, I bought my coins years ago, probably in like the first phase or something. Since I tried to obtain them but with no luck. I have a mnemonic and also a password. Where to I use these so I can actually access the coins I paid for? https://wallet.aeternity.com/ isn’t working and I have no idea where to find my coins.

Hi !!! ERC-20 tokens were frozen on Sept 2019, however there is a mechanism to transfer them to the native ae network ,described in this tutorial. No worries, as long as you have control of your ETH address where you have the erc20 tokens , your coins are safe…
