Conversion 8.1 to 9 timing out & crashing on large files

Hello! I have many scriptcase apps that were built starting in sc5 going up to sc 8.1. I upgraded to sc9, installed it and have successfully converted all but one of the sc8.1 apps. This particular app has over 300 grids/forms/reports/etc in it. When I try to convert it, sc9 stalls after a period of time (less than 5mins) then crashes. My timeout setting is 120 mins for my server as well as my scriptcase app. I’m not sure why it keeps crashing but it does. I’m running Windows 10, 64bit, with Wamp server 2.5, php 5.5.12, mysql 5.6.17, apache 2.4.9. Everything else that is considerably smaller has converted just fine. Any suggestions? I’m wondering if there is a different time out setting that I might be able to adjust. Thanks!
