Hello Ricardo Nuszkowski, The error messages are saying that it failed to initialize your radio hardware properly. It is either gr-osmosdr or SoapySDR (I think this is more likely), not really (the main tree) GNU Radio's fault. I recommend asking the same question on their mailing lists or forums as well. (I think myriadrf is the right place to ask).
The first error message is probably related to this: https://discourse.myriadrf.org/t/limesdr-arrived-but-cant-get-it-to-work/744/11 I am not sure about the second error message - it does complain about your sampling rate settings, though. When the failure happens, the Osmocom source is automatically replaced to a null source, which does nothing. So, you will get an empty WX waterfall window. (by the way, I suggest considering QT waterfall or QT-fosphor, as WX GUI is not supported well anymore.)
