K3 + CAS3 + CAS Studio 7.4

[framas]

Hello,
I need help for the K3 loader with K3, CAS3 and CAS Studio 7.4 version.
What i do:
- connect USB cable
- connect null modem cable
- select phoenix mode 3.68MHz
- run k3 loader
- select the port (COM1)
- no loader fiz connect
- reset file
- and the error message appears: "Unable to restore OS check card"

What I made wrong? Bought I a card without OS?

Thanks
Mantas

I use phoenix mode 3.58 with my infinity usb.

try 3.58mhz and use the latest driver/software for your Cas3.

I left the delay at 200 but I read that you can increase it to 600 (slower).

No, the same error appears.

I have the lastest sw/drivers (7.4 version)
