[mygun2big4u]

I bought GTranslate PRo, installed. made all settings as desckribed in readme file but after I publishing it my site not working. It shows:
Fatal error: Object does not support method calls in /home/xxxx/domains/xxxx.xx/public_html/index.php on line 37
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 2804300802 bytes) in Unknown on line 0

Help me please to configure right settings. I can send you by email user name and password, because I'm not professional.
