This set is not for non-
latency legacy systems i.e. windows xp, vista and 7 is the only support... you could try to email the guy but it looks to me as if he just stopped.
Option 1, get a new windows 8 ps3 device.
Option 2, install windows 7 on vmplayer (
or workstation) and play your games on that... your old ps3c will be happy again.
+ vmplayer = free (
the full version is workstation) and you can use your 8.1 system when not playing the games.
- hyper-v comes free with 8.1 and vmware doesn't play nice with it so you can't have hyper-v & vmware on the same boot.
