Possbly because of the unsupport of TRS2006, when you delete assets.tdx and assets.bku ... and the TAD is updated ... the new files created are instead labeled: assets (in bin), and assets (in cashe) where the original assets.tdx and assets.bku files once were ... very strange.
I tried renaming assets (in bin), and assets (in cashe), to be assets.tdx and assets.bku but this does not seem to be proper ... as if you once again do the TAD update, the files created are labeled: assets (in bin), and assets (in cashe) (although they seem to be TDX and BKU type files).
In short, the the original assets.tdx and assets.bku do not come back labeled correctly.
And the DLS, list of assets that are avilable for download, is very much smaller in your CMP.
