I'm atempting o migrate to ZCM 11 from ZEN 7. I have been successful at migrating all my applications except 1 that fails with the following error?

Exception Thrown Exception of type 'System.OutOfMemoryException' was thrown. in Migrate
Stack Trace: at System.IO.BinaryReader.ReadBytes(Int32 count)
at Apps.AOTClass.GetAllTextFileModifications(LdapEntr y le)
at Apps.Plugin.Migrate(MigrationInfoStruct myMigrationInfoStruct)
Aborting Migration Task
This happens after all the .FIL files have imported fine....

I'm new to ZCM and I'm not sure where to go. I've tried restarting, etc, in the case of a memory leak but that hasn't helped...
