wordpress – WooCommerice plugin error

I recently (2 weeks ago) went live with my GoDaddy/WordPress/WooCommerce site. Its been fine then just now I get this error with the WooCommerce plugin:

An eCommerce toolkit that helps you sell anything. Beautifully.
Version 4.6.0 | By Automattic | View details

This plugin failed to load properly and is paused during recovery

An error of type E_COMPILE_ERROR was caused in line 39 of the file
Error message: require_once(): Failed opening required

What do I do?
