So when is the launch? Sorry, I don't have time to read the pages behind?

It is done. 

Launch time!

Done! launch must be very close!

I am having huge difficulties with the confirmation process. Computer is seemingly not recognizing java, although it is installed and up to date.

I recived my stake through BTT, and registered the stake in time and have all the original info safely stored (public key, private key, address, password, and wallet name), and have not touched the NEM accounts since.

Why would there be any problem now? If I don't figure out how to do this thing, is there a chance I would lose my stake?

PLEASE someone advise me I will send a small tip to you or a charity on your behalf if you are of good help.

I can smell the lauch of NEM. 

$35MM market cap (~1500 sats per XEM)

top 20 in coinmarketcap

Realistically, I think it could be much higher. There are almost no projects with an entirely new codebase and innovation like NEM has. I would expect that 100m is conservative.
