I have just purchased Events + and tried to install it

I have just purchased Events + and tried to install it and it caused a fatal error & stopped all access to /wp-admin. I deleted it and then had access to wp-admin again. i deactivated all plugins and re-installed Event+ and it installed fine - however when i started testing to see which plugin it was conflicting with i found it to be Contact Form 7 which is imperative to my theme.

Do you have any workarounds for Events+ & Contact Form 7?
