Problems running website after updating Easyblog to v5.2.1

Hello,
After updating Easyblog to the latest version 5.2.1 my website can not be started anymore because of the following error:
Class 'EasyBlogRouter' not found

Before updating Easyblog to the latest version 5.2.1 i have first download the full installer package com_easyblog_full_pro_5-10 from your website and install it in Joomla which gives no problems. But when I tried to start the front end it gives; 0 error Class 'EasyBlogRouter' not found

I have tested this in my own development environment and not yet in my production environment (old version is still running there)

Hope you can help me before I gonna update to the latest version Easylog 5.2.1 on my production environment

Thanks!
