well i tryed to remove the Opsis and still the game crashes

Pressure Pipes is broken. Try updating to a newer version, the one you have is quite old.

Update BdLib, Advanced Generators and any other of bdew's mods you have installed.

Update BuildCraft Additions and Eureka.

Did update all builcraft mods but can i find Eureka mod? (can you be spesific) is it named someting else?

google is your best friend https://www.google.nl/#q=Eureka+mod

Sorry Loordgek i meant so say how do i find it (cause i cant find it)

The mod is literally called Eureka. It's required by BCA and available from Curse.

It's ok i found it (the hard way). the file was invisible in the Mods folder so...

Binnie's Mods (Extra Trees, Extra Bees, Botany and Genetics) don't work with Forestry 4.x.x yet. Either use an older version of Forestry (may cause incompatibilities with other mods) or disable Binnie's Mods.

 

You've installed a Cricket version of Chisel Facades with a Chisel Team version of Chisel. Update Chisel Facades to the latest Chisel Team version.

 

Another One Bites The Dust, More Chisels and Extra Cells have also errored in some way, make sure you have the appropriate dependencies installed.

well i tryed to downgrade the forestry but i get  an  Any: Forestry 4.0.0.0 so ... and i dont want to remove Binnie's mod and it still doesent work when i remove Binnies mod

 

 

Post the log and crash report with the old Forestry version and Binnie's Mods enabled and/or with the new Forestry version and Binnie's Mods disabled; otherwise I can't help you.

Both your old and new logs appear to be using Forestry 4.1.1.46. In addition, you seem to have posted the contents of the vanilla log (latest.log) instead of the Forge log (fml-client-latest.log), which contains a lot of useful information not present in the vanilla log.

 

If you want to use Binnie's Mods, you'll need to use a pre-4.0 version of Forestry. If other mods need a newer version of Forestry, remove them or use older versions.

The versions of ExtraCells and OpenComputers you have are incompatible. Update OpenComputers.

How do i find the mods that require does mods?

 

How do i find the mods that require does mods?

 

Most mods will list their dependencies on their website/forum thread.

 

If a mod depends on a different version of another mod than the one you have installed, it will simply crash (either because its specified dependencies aren't present or because the version you have installed does something differently to the version it requires).

 

If a mod's dependencies aren't present, the log will tell you the name of the mod and the names/versions of the missing dependencies and the crash report will tell you the names/versions of the missing dependencies.
