Think ive found out why Kalypso patch not working.

[Sneaksie]

No, in Russian version you had not to have the disk in drive.
Many of those people who had problems with Kalypso patch installed it on GoGamer version of the game (which is not Kalypso and imported from South-East Asia and have a separate patch). We've tried the Kalypso patch with several ToW Kalypso DVDs we have and it worked. The only possibility left if some people still cannot play the Kalypso version with correct patch is that there is a different release with different disk parameters but we don't have any information about it.
