Did you encounter this after updating SimplyJetpacks? I updated from a quite old version to the latest, then I started getting errors like this.

[bookking3000]

I didn't uptade it, since i was using the FTB Infinity Evolved Modpack(1.7.10), which uses SimplyJetpacks 1.5.3. I think 1.5.3 is the latest Version available, i didnt test it on lower Versions.
