Just got a 'Fatal Error' for Events+

My site randomly just went to a blank page rendering wp-login inaccessible. I renamed my theme folder, as well as the plugins folder via FTP and access was reinstated. Except upon reactivating the plugins, Events+ generated a Fatal Error.
I'm exporting my database now, so no worries on that. Is this going to be a quick fix kind of thing or should I tell my client we're stuck in the mud for the time being?
