TMS VCL UI PACK v12.1.0.2 canot build application for XE7

Hi I downloaeded TMS VCL UI PACK v12.1.0.2 today. the setup uninstalled previous version before install the new one. after that my project wont link any more due to the following error:
[ilink32 Error] Fatal: Illegal EXTDEF fixup index in module 'AdvPersistence.pas'

But once I went back to TMS VCL UI PACK v11.0.0.1, I can build the applications without any error.

TAdvListBox, or TAdvDateTimePicker might caused this issue.

Can you please check this?

I retested this here in XE7 but couldn't see an issue when adding a TAdvListBox to a new project and/or adding the unit AdvPersistence to the uses list.
Is this error happening when you add these to a new project?
If this is happening in an existing project, could you give more context & details?
