Replication or save Conflict in Profile Documents

I recently downloaded the free scanEZ Getting Started with scanEZ to help with a problem in a mailfile and I saw that I had a save or replication conflict in my profile document… and I must say the info made available in this tool is HOT. I rented the tool today to fix the conflict but want to prevent this in future. Does anybody have expirience why something like this happenes? And more important how to prevent this from happening again. Thanks for your help Markus
