Flightscene simconnect issue

[Danno 192]

I’m not sure this issue is fixable but it’s worth asking. Last year, I bought the Tahiti scenery package from Flightscene. However, in FSX, the scenery DLL conflicts with other DLLs. The author says it’s a result of older simconnects loading before the newer version that Flightscene requires. I’ve tried re-ordering entries in the dll.xml as well as the items in the Trusted section of FSX.cfg. No luck. 

I can get it to work if I delete everything in ‘Trusted’ except the Flightscene entries but obviously that’s not an option. Almost every payware product adds its DDLs or gauges and once I start accepting those files as Trusted, I’m back to where I was. 

I’m told there are 3 versions of Simconnect in FSX. Can I remove whatever the two oldest ones are?
