If one works and another doesn't, it's probably either a setup problem or a firewall problem.
If it were a firewall issue, why can I see the server and the files therein?
it worked before I entered the new license key so a firewall issue seems remote.
I am sure it is a setup issue as
the setup was not the same as on the other two laptops. The other two laptops did everything themselves automatically when i clicked on the key.
This laptop did not. I had to wrestle it to get as far as I've gotten.
-------------------
I have already uninstalled and reinstalled.
I'll do it again if someone can walk me through it.
I followed the links for setup that were left and that got me closer, it enabled the client to see the server files and play them. I am not new to this, I have been around since MC18.
I understand it was only another $50 dollars but if it does not work, it's like burning money.
Nevermind the vast amounts of time, now and in the past...
