In December 2011,  I obtained Notion 3 (Boxed) via a Cakewalk offer and in January 2013 the upgrade to Notion 4 (download). Both were installed with offline authorisation.
 
On 2014-04-23 my email address was changed over to another because my ISP was discontinuing business (email addresses gone), I received confirmation of changeover from customer support.
 
In September/October 2015 I obtained a new computer which I connected to the internet and did not transfer Notion 4 over to it.
 
Since Cakewalk Sonar Platinum might be no more, I decided to check my Presonus account and look at Notion 6 and Studio One 3.
 
On 30th November I tried logging into my account where I previously downloaded Notion 4 but failed, account did not exist. So I emailed customer support from my last Presonus email received. One week later no reply to email.
 
On 8th December I sent another email asking for advise, should I re-register products. Today (15/12/2017) no reply.
 
So today I recreated my Presonus account and tried to re-register my products. For Notion 4,  I get " This product key has been registered already. Please supply an unused product key." For Notion 3 reqistration requires 20 or 28 digit licence code, in box Licence card for Notion 3 has a 19 digit code.
 
Today (15/12/2017) I sent off internal support ticket to Presonus to get my products on my account. I will wait to see what happens.
 
Previous support for offline activation from Presonus had been good.
 
 

If this is about PreSonus issues, you're in the wrong place as this is the Cakewalk forums.  You're probably best redirecting your query to http://www.presonus.com and finding the support pages there.

Yeah, don't think anyone from Presonus is checking this subforum kinda curious, why here? Is this a warning announcement? Presonus does have problems with support especially during the holiday season being their really not a giant conglomerate(i.e. Gibson, ect.). In my experience they do a fair job though and you may be experiencing a unique situation.

Hopefully your issue will be addressed. if you are able too, post in the pre sales forum there at the Presonus forum, they definitely keep an eye on that one.

Edit: Doh I just checked that forum and it is blocked for support issues. So never.mind that forum. I guess a support ticket is the best solution as all the other forums are community User's and your topic may or may not be seen by the staff who can help. Once again, hope it gets addressed too your satisfaction.

Perfectly reasonable to post this kind of info here, considering people weighing their options. Not to mention that things like this are now a very REAL concern (support) given the example gibson has set.
 
Do hope it gets resolved.

That all remind me all these threads about CW support, accounts, registrations, "demo" modes...
 
I am glad that I have learned the lesson and switched to the DAW which has NO registrations, accounts, special upgrade prices and all the other mess which can be forgotten or changed

We're not saying it's unreasonable, just saying he won't get his issue resolved here! 

Presonus responded to my support ticket and account working as before, can access Notion 3 and 4.
