Are you sure?
I just downloaded the ECAT 2.2 and installed using the Option 1 using the link below.

No version 2.0 attached.
Also, I used the same configuration with you (LV 2011 + NI-FIO 4.0).
The time for me is about 1 hour including download and installion.
Could you please try again when the internet is not busy?
Thanks.
