I'm am not familiar with this error and I can't find any reference with it in regards to TrueDBGrid and the XArrayDB. I found references to other COM components and typically was the result of a OCX or DLL file not being properly registered.
I would suggest starting there. Assuming your on a 64-bit machine, navigate with a command line (with admin rights) to C:\Windows\SysWOW64 and run "regsrv32 xadb8.ocx". https://help.grapecity.com/componentone/NetHelp/truedblist8/redistributablefiles.html
This may re-establish the registration of the OCX file and resolve the error.
