Try & Decide trapped in a loop - discarded all documents

Hello, I am using Acronis "True Image Home 2010" on a Windows XP Home (SP3). I was running "Try & Decide" for several days to install new software. After restarting Windows (Try & Decide enabled) the computer dropped in a loop offering to continue trying or to discard all changes and reboot. To stop the loop I had to discard all changes. The problem: Try & Decide discarded all documents (Word, PowerPoint, PDFs, etc.) I was working on while Try & Decide" was running. I have no backup. Is there a chance to get these documents back?
Thanks in advance for your help!
