I try to Enable it. But, i cann't!
Has it ever worked, or did it just stop working for you one day?
For me it worked for some time and now I have the same problem as you : /
Typically, if you were able to record and then all of a sudden it stopped working, it may have failed the benchmark test that it does periodically. If that happens, we recommend seeing if you can change the IQS_index in your cfg file to see if that helps: LINK
If you're unable to make the changes, don't have iqs_index in there, or it has never worked for you: it could be something else.
