DTM messing up services?

Ok, where I work, I can DL the DTM manager, but it comes with preset options. When I plug in my BB and use the DTM (to install themes) it resets my MMS and Yahoo IM. I was on the phone with Sprint and they couldn't help as my account is provisioned correctly. First thing I did was a handheld wipe, but that didn't work. So I deleted the service books that are used for the DTM, MMS, and Yahoo. I then did a master radio reset, then a hard reset. Next, I sent myself service books and then registered with the network. That seemed to have worked last night. This morning, I used the DTM, to see if there are any options I could change to prevent this and I am running into the same problem again, only this time my fix didn't work.

Any suggestions?
