Indexhibit Support

I'm installing the new indexhibit. I upload the files, change the permissions and when I go to my browser to start "the installation" got this message:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/ah000062/public_html/ndxzstudio/lang/index.php on line 14

I re uploaded "lang" folder, I reuploaded indexhibit 3 times... no luck, always the same message. I only need english or spanish. What I have to do?
Thank you very much.

I feel confident in editing the php file, if you told me exactly what and where. Thank you.

I'm reading the old threads...sorry, I didn't see them before

I fixed it changing to php 5.3.10
