NathanKell : thank you for your reply. Today I try EI v3.2 and RF v6.0 or v6.1 or v5.3. I deleted the folders every time. Then I can play limited ignition with EI v3.2 and RF 5.3. I use only one Module Manager dll v2.1.5. I think RFv6 has something which cause the trouble. Thank you for your reading.
The EngineIgnitor.dll can't work because of the RealFuels.dll. During I use RealFuels.dll, the counter of Ignitions:Electric 1/1 doesn't change. I can ignite all engines infinite times. How can I make EngineIgnitor.dll work well?
