LiveCloud libraries fail to load in LC Create DP6 "Classic"

I was expecting this not to be a problem, but when opening a LiveCloud-based solution in LCC “Classic”, the canelaDB libraries fail to load with the error:

This same application works fine in LiveCode 10.

I wanted really to use some controls from LCC classic, so I did the silly thing of copying all the extensions embedded within LCC and dumped them in the extensions forlder for LC 10. Sure enough then all are present then - but when I tried to then load this same app that used to work in LC 10, it now shows this same error from LCC.

I guess this means the extensions are someone creating an issue loading these libraries (perhaps something to do with TSNet?)

Grateful for advice
