I believe I had the same issues. Hopefully these steps help.
1: Do you have Emotiv Pro? If so, export your data as edf and not csv.
2: In EEGLAB, you may need to try any other biosig, biosemi or edf file importer…. Sometimes, one will work while others won’t
3: Once you can input the channels, include channels “1 2 3 4 5 6 7 8 8 9 11 12 13 14 15 16 20″…Channels 1 and 2 are counters, channel 20 are for events.
Let me know if that helped at all
