ISI today released version 1255c of rFactor (download here). This removes the external company managing purchasing and activation of the product, and instead is managed by ISI. Everything else, including the activation policies, remains unchanged from the old 1255.
The new system is very simple. In the image below, Purchase is where you get the Product Key, and Activate is where you use it.

Purchase (buy Key), Activate (use Key) options.
Notes:
- The free trial system remains intact. Try before you buy.
- New purchases of rFactor can use the new system immediately by downloading 1255c.
- Old purchases of rFactor can be transferred easily using this form and your Purchase Order Number.
- All 1255 versions are compatible with each other online.
- There is no need to update your installation from 1255 to 1255c, unless you need to freshly reactivate.
