UT Crashing After Deleting Custom Maps

I was experiencing some odd behaviors connecting to a test server, so it was suggested I remove any custom map .pak I had in the various folders below:

C:\Program Files\Epic Games\UnrealTournamentDev\UnrealTournament\Content\Paks

Seems pretty innocent. Right away I tried to launch UT and I immediately get the following crash:

"MachineID: BAE587D34B69B064C71E2682C53384B4.
You do not have any debugging symbols required to display the callstack for this crash"

I only deleted .paks for custom maps including my own. Why would this affect UT from even launching?

I’ve attached my system info in case it helps. I am on a Mac running Bootcamp, but the only issue that would bring up is graphics card drivers.

Any help would be appreciated.Thanks.

OK, so after hitting the Verify option on the UT game a couple of times, it seems to have fixed my problems. Everything is now working as advertised.
