Yesterday I backed up the profiler and deleted about 200 rigs from it using Rig Manager. The next time I booted up the Profiler and launched Rig Manager, the syncing process started and went on for about 40 minutes. When the process finished the Rig Manager said there were 540 rigs on the Profiler. If I scrolled through the rigs on the profiler it said that I had 740 rigs e.g. "650 of 740 rigs" etc.
I had already read of the problem on this thread so I took a copy of the DebugLog.txt file and also ran a backup of the profiler using a USB stick. I copied the backup file to my PC with a view to sending it and the log to Kemper Support to help them identify and fix this problem. I then noticed that the new backup file was only 2/3 the size of the backup file I had taken before deleting the 200 rigs! I unzipped the file and saw it only had 540 rigs in it!
So I immediately restored the new back up file to the Profiler and "Hey Presto" only 540 rigs were restored and when I relaunched Rig Manager the syncing process was a only a matter of seconds! My profiler did not crash at any stage.
Hopefully this information will help solve the problem of prolonged syncing. I still have the text and backup file if they are of use to Kemper Support.
