Fatal Error – Change WooCommerce Add To Cart Button Text

I installed the plugin Change WooCommerce Add To Cart Button Text but when I try to activate, I get a fatal error. Details below. Can’t seem to find another plugin that would be causing this. Theme we are using is MasterStudy and it causes the Add to Cart button to read Enroll this Course (we are a school) and wondering if the two are related. Really just want to sell play tickets so Enroll this Course needs to be changed or we can’t use WooCommerce. To note, I tried another plugin that also changes the button color and while it changed the color, it did not change the text. There was no error upon activation.
Error Details:
Fatal error: Cannot redeclare woo_custom_cart_button_text() (previously declared in C:\Inetpub\vhosts\smsvb.net\httpdocs\wp-content\themes\masterstudy\inc\woocommerce_setups.php:282) in C:\Inetpub\vhosts\smsvb.net\httpdocs\wp-content\plugins\change-woocommerce-add-to-cart-button-text\change-wc-button-text.php on line 18

Not really good with WordPress so any help would be great. Thanks
