Dear Agnes,
Sorry to read about the troubles you're having while purchasing. The assistent code is automaticly generated by the subscription system but does not refer to any usefull information ;-(
I've just tried to buy a license for BCA Plus and all works fine; I used a normal, just registered, useraccount and I do get redirected correctly to PayPal and the license get's activated correctly.
Most of the time the Assistentcode also appears when a field isn't filled correctly during the license form proces. Could it be you're missing a required field? These should be marked red but it might be you need to scroll down a bit to see it.
If that doesn't work either, please let me know, we'll fix the license using the manual method :-)
Greetz, Nikolai
