In certain circumstances, problems may arise with XP SP2 beta, in this case you need to upgrade to XP SP2 release.
Thanks for the clarification Drealmer - but does this not still indicate that Starforce can cause compatibility issues with future Windows updates?
Yes, it indicates that Windows service packs and releases can be incompatible with StarForce... *BUT* it also indicates that Microsoft cares about StarForce, because the compatibility problem has been explicitely solved on the final release of the SP2.
Will Microsoft continue Windows support for StarForce in the long time ? I can't tell the future, but since StarForce is used by more and more games each day, Microsoft would not do a smart move by saying "hello, here is the new Windows, please buy it but notice that 95% of your games wont run on it"...
