When I manually try to compile xdata280.bpl i got error in XData.Aurelius.Modelbuilder in line 907
The error indicates that you have an outdated version of TMS BCL. You should uninstall, download the latest version and reinstall BCL (and Aurelius and Sparkle), before installing/updating XData.
If you are sure you have already done that, then maybe your TMS Subscription Manager cache got corrupted.
In this case, close the Subscription Manager, go to folder C:\Users\USERNAME\AppData\Local\tmssoftware\ (where USERNAME is of course the name of your Windows user) and delete all folders there related to TMS BIZ (you can actually delete all folders with product names, that’s where the downloaded installers are).
Then try to download and install everything again.
