Hello all. Just wondering if anyone can guide me on this. I own a boxed version of Wavelab 2 and want to upgrade to the current one. Did a new user registration at the Steinberg site and it didnt recognize the old serial number. Any info on this will be much appreciated 
There’s no upgrade path for Wavelab 2. You need at least Wavelab 7 to get upgrade pricing.
Also, a Wavelab 2 serial number is probably too old to be recognized by the site system.
You should try logging a support request in MySteinberg / MySupport, it’s worth a shot but I wouldn’t hold my breath. That’s a really old version! As you’re new here, it’s worth mentioning that this is a user-to-user forum, although Steinberg staff are sometimes active here (including the great PG himself!). Sales enquiries must be directed to Steinberg themselves.
