Fatal error: Allowed memory size of 41943040 bytes exhausted – Help!

I just installed Enfold theme and when I go to activate it – slideshow.php is blowing up. Here is the exact fatal message I get and below that the line of code. Copied from line 493 to 500. For a new client who specifically picked out this WP theme so suggestions on how I can get it working would be greatly appreciated.

Error message —
