Incremental Backup

I wish I would have seen this forum before I purchased Acronis 9. I read such good reveiws of version 8, I decided to buy it.
What a headache!!!!!
This what I get now on trying to do an incremental backup

An error screen and the operation stops.

AppName: trueimageservice.exe AppVer: 9.0.0.2277 ModName: trueimageservice.exe
ModVer: 9.0.0.2277 Offset: 0004690b

This frustrating. The error message is in the previous post.
Today however the "manually" scheduled task of an incremental backup worked with no error screen. I also have the latest build 2277.
Thanks for the reply.
