ADS1299 EVM acquiring and reading registers issues

Other Parts Discussed in Thread: ADS1299

Hello, I have 2 big troubles using my ADS1299 EVM

I installed the latest software (ads1299-eeg-fe-1.0.2) correctly on Windows 8, rebooting the machine with Signed Driver Enforcement disabled. The drives of module are also installed correctly, the device manager recognizes it  as MMB0 (NI-VISA).

When I run the software, it shows "Connected to EVM", after that it starts to reading registers (this takes a while), then it shows "Sync Complete...Ready"

Everything seems to be ok until now, but when I click on "Register Map sub-tab" on  "ADC Register tab", ID Register has a 00 HEX Value, and when I manipulate an ADS1299 configuration like a GPIO or enable SBR1, nothing seems to change, and "Register Map sub-tab" does not update itself.

Another issue that I found, is that when I click on Acquire or Continuous buttons, the screen "freezes" in gray and shows a pop-up with an error message, and then I can't do anything.

I tried to probe the EVM on another machine with Win 7, but it's the same thing, then I probed it with a Win XP machine but I couldn't install the dirvers, the installation wizard shows an error with mmb0_visa.inf file.

The configuration of the board is the same of indicated on page 17 of the EEG Front-End Performance Demostration Kit User's Guide, Single Ended Inputs.

Please, Can anybody help me?
