You're right I didn't had to use the command -cli and without that it worked and I received the coins from the former wallet. Many thanks!!

Downloaded the latest version and synced for quite some time. Entering in console myriadcoin-cli importprivkey "myprivkey" lead to error: Method not found (code -32601)

But where can I find the Myriadcoin-core (is that the Electrum app)? And also where to find the debug console where I propably can find the "importprivkey" ?

I mean XMY off course

Sorry for the late response, but this is the case:
I have an ‘old’ cryptap.us wallet and have all the (secret) information about this wallet. When I enter https://jswallet.github.io/#[myprivatekeyfromthiswallet] I get a screen in a myriadcoin jswallet with a new myriadcoinadres and don’t know how to proceed. Can you please explain in steps what I have to do from there so I get control over the XMR-coins in my (old) wallet?

Again many thanks, but as you probably notice I'm not that experienced. I do have the private key and when I use this in https://jswallet.github.io/#ThisIsYourSecretBrainwalletTextstringDontShareIt I get a screen of "myriadcoin jswallet" with probably a new wallet address ("myriad coinaddress") with 0 amount. Do I need to send my coins to that address and how can I do that. I'm also wandering how I can open that (new) wallet because there is no seed or private key.

I tried this and it seems to open a new wallet, but I don't see any privatekey or passphrase. I probably have to move my (coins of my) old cryptap.us wallet to the new github wallet, but don't succeed in this. I also tried to send my amount to an address of my broker, but also withou result. Can you explain waht I have to do?

Ik heb voor dat cryptap is overgegaan van cryptap.us naar cryptapus.org een een wallet aangemaakt en daarin MYR-coins opgeslagen. Nu probeer ik een tx te doen, maar krijg dus steeds de melding dat mijn source adres  https://cryptap.us/myr/pushtx/index.php  niet klopt. Als ik deze dan aanpas naar https://cryptapus.org/myr/pushtx/index.php verschijnt evengoed de melding cryptapus.org vertelt: something went wrong...
Wie kan mij helpen?

I recently noticed that still I have some XMY's in a wallet of cryptap.us since 2017. Now I can't transfer them. The name of the site in now cryptapus.org but I get the message "press OK to send the message to https://cryptap.us/myr/pushtx/index.php" but after ENTER I receive the message "cryptapus.org reports:  Something went wrong". How can I transfer my XMY which are created in a wallet in cryptap.us or else?

Many thanks for the reactions. It sure is some time ago, but I had forgotten them (how could I?). I have all the information/codes, but apperently it goes wrong because of the changed site. Does anyone know where to reach someone from cryptapus.org?
