The problem with the SMOKE_GEN modules is most likely that they were compiled in DEBUG mode rather than RELEASE mode, causing them to depend to rely on debug versions of their dependencies.
A quick recompile of the modules in RELEASE mode ought to fix it.
For now a download of MSVCR90D.dll should fix the problem temporarily: http://www.dll-files.com/dllindex/dll-files.shtml?msvcr90d
Let's be clear, you don't have particle effects using Velcro Rockets under Orbiter 2010. It's why I needed additionnal .dll modules (implemented in the scenarios as dummy invisible & almost weightless ships) to bypass that limitation. Recompiled "release" .dll will be available in next versions (1.01 for the russian DGL).Could it possibly be a bug in Velcro rockets caused by Orbiter 2010?
