How to? Installed v18 Beta - how buy/register?

#1
Hello TC team

I have successfully installed the brand new v18 Beta.

Now, for each start the message appears, that the program is valid for 30 days - and "you can buy/register it on webpage" or something like that ...

I pressed the BUY button, but there was only a possibility for v17.x ...

And now?

Thank you.

PS: I know, it's the FIRST beta, nevertheless I will buy/register as soon as possible :-)
