Translated by Google:
The other day, I purchased Total Studio 2 MAX Maxgrade from
https://beatcloud.jp.
Since I have Amplitube4 Max, I bought it because I can meet the conditions of MAX Maxgrade
Did.
I entered the serial number sent by IK Product Manager.
Server Error: Serial Number not eligible for crossgrade / upgrade (code: 207)
Message appeared and I could not authenticate.
I've also contacted support, but haven't heard back yet.
I am posting here thinking that it can be solved.
Please tell me how to solve it. Thank you.
Just for readers' info, from
https://www.ikmultimedia.com/faq/?id=1191What is a MAXgrade?
A MAXgrade is a discounted price for users who own another specific qualifying IK product or collection. A MAXgrade will allow users who own larger collections to expand into different ranges of products, this is a more specific path with a deeper discount than Upgrades. To qualify for a MAXgrade to another product, you must be registered with a qualifying version of that product. This allows for serious IK users to expand their collections at a discounted price.
There is no loss of a previous license, only a discount!
An example of an MAXgrade would be if someone owns the AmpliTube MAX software collection, but is now interested in Total Studio 2 MAX. Instead of purchasing the full version, a discounted MAXgrade option is available at a lower price.
That last sentence seems to match you 100%.
