I answered this question as reply on a direct email you sent with the same question.
This was the reply:
I see the error in the structure pane and it looks like either you installed the trial version of TMS WEB Core or you have not uninstalled the TMS WEB Core trial fully before installing the registered version.
Please scan your full hard disk for files js.pas and js.dcu.
There should be ONE copy of JS.PAS in the subfolder Component Library Source of the TMS WEB Core install folder. This subfolder should be in your IDE library path.
Then also scan your full hard disk for all copies of JS.DCU and make sure there is only ONE copy and it is the copy that belongs to the latest version of the registered install and when multiple copies are found, delete ALL copies that are not part of the latest TMS WEB Core registered version install.
