dude it’s just a software error. reporting it to elektron is the right thing to do. there’s no reason to get worked up about it.
the very reason error messages like this exist is to give developers hints about logic errors in a program. All programs have bugs. If they are reported, developers can fix them. and the world keeps spinning. 
I have taken a different approach - I took the machine back to the store (in Vienna) and got it immediately replaced by a new one. The new one works perfectly so far !
Well, I just opened a service ticket with elektron since it happened again 
does anyone know if they take a long time to reply? I opened the service request 2 days ago.

I am in the USA and anytime I have contacted support, it usually was always within 3 days giving the time zone difference and never know what holidays they may observe, just hand tight, as they always respond reasonably time-wise.
Thanks namnibor, today is 2 days since I messaged them so there’s still some time until they reply. Thanks for your answer though, gives me peace of mind and reassurance that hopefully something good will come out of this, thanks again!

Ok thank you tertior and everyone else providing feedback. I’m not sure how to enter test mode though but I’ll try to figure that out first. I’ll let you know what happens afterwards. You also mention there is a post by JGB? Is this on how to report these bugs to elektron? Thanks.

OS here: Analog Drive | Elektron
I recommend to upgrade to 1.06.
The bad news; I couldn’t get my a4 to work with the rest.
The good news; I sent it to the repair center here in the US and elektron fixed it!!! Problem solved. They took a little long (about 1 month) but fixed it at no charge and did an amazing job! I’m so happy!
Thanks to all that gave me feedback as to how to proceed.
Did they tell you what the problem was?
Well, the part that they replaced was the “AF IOCPU.” They didn’t give me details but I’m assuming this is the part that wasn’t working.
Yes I got that message. My pattern delete works, but the undo doens’t work. It pattern deletes twice, then undo, but it’s too late cause I’m undoing the second delete.
Once when trying to get undo to work that message popped up.
No, not necessarily. Faulty hardware can also result in software exceptions. Never had a PCI card fail in your PC back in the days?
