Ex Compressum crashes?

Whenever I try to open Minecraft 1.7.10 with Ex Compressum it crashes and I'm told that something is wrong with the Compressed Hammer or that it is responsible for it.

Try again with another version of this mod, restart your PC and see if it works. If it doesn't work, change the version of Ex Nihilo again because the mod is important for Ex Compressum. If it still doesn't work, delete and reinstall Java.

Thanks it works now.

Now I have a problem with Botania. The crash report says something about TinyPotatoeRenderEvent. I have tried an older and newer version of Botania and downloaded Baubles again.

I reinstalled Ex Nihilo.

If you have Ex Astris:

Change the version once

Write to me if it works

What is Ex Astris?

Can you answer this question for me too?
