[Eeglablist] Error booting up EEGLAB

[Lisa Bartolomeo]

I discovered this same issue today, Graham.

Removing the Biosig3.8.4 folder from my eeglab plugins folder made eeglab
start like normal, but then of course you can't import any .bdf files. The
plugin page is still down (
https://sccn.ucsd.edu/eeglab/plugin_uploader/plugin_list_all.php ). Did you
report the problem to SCCN using their contact form? If not, I can do so
and let you know if I hear anything.

I also checked the BioSig library (
https://urldefense.com/v3/__https://biosig.sourceforge.net/download.html__;!!Mih3wA!BOEZmXt860HuYjNLziJDfaNlRAvMkgCWqtuobvKNpOOFpR7s7BTE7wbTGsjDFzefeT60o91ofrDri1iLcS9TuJHBQZLs$ ) and there's not a download
listed for MacOS, which is what I'm using. If you're using Windows, maybe
the v3.8.5 download would work?

If I make any progress in troubleshooting this, I will send an update.

Thank you,
Lisa
