Hang-up when importing data (no replies)

My new wampserver is a go. I an trying to load a particularly large file into a php/mysql program called webtrees by importing it. However, none of the data (blobs) are being loaded into the mysql table as they should be. Is there some "time-out" value in either apache or mysql that might prohibit the loading of the full file (approx 72mb). If there is which values do I need to change in the config/ini files to increase the time-out value?

The program I am using requires a newer version of PHP 7.X. Is there a way of upgrading php in wamp to version 7?
