Need Help - SMF Gallery lite

[newguyatthis]

I am a new user in SMF, i have my forum up already and i am attempting to install packages.  The main package i am trying to install is gallery lite.  i followed the instructions posted on your website but i'm still lost.  Please help.

First i am using OS Mac w/ Safari web browser.  I dont really know much about this so please bare with me.  I downloaded the package gallery lite to my forum by linking it to smfhacks.com and it showed up on my packages.  i pressed apply mod and it displayed:
1.   Execute Modification   ./Themes/default/languages/Modifications.english.php   Test successful
2.   Execute Modification   ./Themes/default/languages/Modifications.english-utf8.php   Test successful

12.   Extract File   ./Themes/default/languages/Gallery.english-utf8.php   
13.   Execute Code   galleryinstall.php   

only items 8-13 have no Test successful.  I also went to my webhost file manager and changed the permission of the (42Gallery1.8.2.zip) file of gallery lite to 777. 

Then i click "install now" my web browser begins to load and ends with this message:
Safari can’t open the page “http://respiratorychat.com/index.php?action=packages;sa=install2;package=42Gallery1.8.2.zip” because the server unexpectedly dropped the connection, which sometimes occurs when the server is busy. You might be able to open the page later.

Someone please help me.

i found this error log on my forum site:
