Replay Gain Problem

I’m using the Replay Gain on my music library. All goes well until UM reaches folder 2000 then it gives an Exception Access Violation message and then asks if I want to attach Visual Studio to process 1280. Each time I say yes it fails then closes UM. If I select no it also closes UM. I’ve tried deleting the folder that seems to cause the problem but UM simply fails on the next folder being adjusted by Replay Gain - always folder 2000. Any thoughts on how to finish performing Replay gain on the rest of my library? There are over 25,000 mp3s to be done.
Thank you,

Do you mean folder 2000 or the 2000th song?

It is folder 2000
