We've recently switched the Zorro S subscription system from keys to tokens. If you have subscribed Zorro S from Digital River, you should have received an email with a 20-digit number last week. Enter that number in Zorro.ini under "ZorroKey" and remove the previous key file from the Zorro folder. The old key files will automatically expire by the end of the month. Running sessions need not be interrupted, and permanant licenses or subscriptions through affiliate brokers are not affected by this.
The new system requires Zorro 2.15 or above, so if you want to use an old Zorro version with your subscription, please contact Support for a replacement key file.
