[Programming Help] - ACSIL full market depth stopped after upgrade from v2909

My custom ACSIL study used to read full market depth correctly on v2909 using: `sc.UsesMarketDepthData = 1` `GetBid/AskMarketDepthNumberOfLevels()` `GetBid/AskMarketDepthEntryAtLevel()` After upgrading Sierra, the study’s BOOK/PRESS depth signals went blank. The Market Depth Window still shows depth, but ACSIL full-depth reads no longer return usable multi-level data. I rebuilt the study with the newer headers after the v2911 `s_MarketDepthEntry` change from `float` to `double`. The rebuilt DLL is definitely running, but full-depth reads still fail. I added diagnostics and the study now only works via a level-1 fallback using `GetSymbolDataValue(..., SubscribeToMarketDepth=true)`. Message Log also shows: `SC Data with Depth \| Logon error received from server: Data service (scdtcdatawithdepth) is disabled or unsupported.` Is there something I can do to fix this? Thanks.
