Symptoms:
When the format painting is broken or missing, the ITD is prevented from being rebuilt. Consequently, the content from the matches from the Machine Translation engine are reverted in the SDL TMS database and therefore they are not included in the ITD file. 

Explanation:
After matches are returned from the Machine Translation engine, they are transferred into the ITD file. If the format painting is broken, this transfer cannot happen. The merge mechanism is not tolerant of missing format painting and as a result, the changes coming from the Machine Translation engine are rolled back.

Resolution:
The fix makes SDL TMS more tolerant for format painting mismatching and therefore matches from the Machine Translation engine are kept.

SDL-hosted customers should contact SDL Support to arrange for a hotfix to be deployed.

Customers who host TMS themselves should download the installer for SDLTMS2011SP5CU1 Hotfix for TMS-5198.exe from the following FTP site: ftp://sdlpatches:5dlpatch35@ftp-emea.sdlproducts.com/SDL TMS/2011 SP5/CU1/Hotfix.
