Please try to delete the "cache" for installers:
In the Subscription Manager, click the settings icon in the upper left corner.
Then you will see the location of the "Data folder".
Click the folder icon to open the folder in Windows Explorer. There you will see several folders, one for each TMS Product. The installer of the TMS XData is there. You can simply delete the XData folder to force the installer to be downloaded again. If you want you can delete all folders there to make sure the manager will download new installers.
Once you do that, then try to download the installers and reinstall XData.
