Error finding gateway after compressing files on mac

I am trying to compress the files in the trunk folder of my plugin, so I can upload the plugin to my test www.remarpro.com website.

I have done the compression by using “Compress” when viewing the files in folder on my mac. I have also tried using:

zip -r myarchive.zip .

from the command line.

In both cases, I am getting the following error – stating that the MeprTrelisAPI gateway is not found – when activating the plugin:

Fatal error: Uncaught Error: Class 'MeprTrelisAPI' not found in /home/customer/www/staging2.shop.trelis.com/public_html/wp-content/plugins/aprilthirdsecond/admin/MeprTrelisGateway.php:100 Stack trace: #0 /home/customer/www/staging2.shop.trelis.com/public_html/wp-content/plugins/memberpress/app/lib/MeprGatewayFactory.php(18): MeprTrelisGateway->load(Array) #1 /home/customer/www/staging2.shop.trelis.com/public_html/wp-content/plugins/memberpress/app/models/MeprOptions.php(964): MeprGatewayFactory::fetch('MeprTrelisGatew...', Array) #2 /home/customer/www/staging2.shop.trelis.com/public_html/wp-content/plugins/memberpress/app/controllers/MeprStripeConnectCtrl.php(166): MeprOptions->payment_methods() #3 /home/customer/www/staging2.shop.trelis.com/public_html/wp-includes/class-wp-hook.php(308): MeprStripeConnectCtrl->mp_disconnect_notice('') #4 /home/customer/www/staging2.shop.trelis.com/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #5 /home/customer/www/staging2.shop.trelis.com/public_html in?/home/customer/www/staging2.shop.trelis.com/public_html/wp-content/plugins/aprilthirdsecond/admin/MeprTrelisGateway.php?on line?100

Oddly, when a colleague compresses the same files in the trunk folder on windows, there is no issue activating the plugin.
