Error Message When Activating wpmudev-updates

After upload via FTP, I clicked on "Activate" and my Wordpress Admin screen went blank. Only this error message was displayed:
Parse error: syntax error, unexpected '}' in /home/public_html/blog/wp-content/plugins/wpmudev-updates/includes/notifications.php on line 49

Could you, please, help me fix this issue?

Thank you very much.
