On the Crazy Light Tools disk, run "preferences 3.0" or click on "configure editors" in the loader menu.
If it says "Sprache:de", click on it to change it to "Language:en", which should be already the case when you downloaded it from my homepage.
If you only want classic elements, you want to set "User skill:novice". Then click on "Save this setup". All editors should be English now.
Right after the download link on my homepage:

There is a tutorial video on how to use the Construction Kit and create a standalone game afterwards.
For designing graphics for this engine, you need to use the Enemydesigner 3.0, which is also present on the Crazy Light Tools disk. The original No One version is not Crazy Light compatible. If the Crazy Light version is stuck with a cursor at the file name, it means that the file you tried to load is not compatible. Unfortunately, there is no graphics converter between these versions. If you want to do it manually, check out the RAM layout in my Dash FAQ:

In case you're using JiffyDOS, be aware that my directory routine does not work with it. My JiffyDOS mod for Dolphin DOS is also affected by this. This is something on my todo list. Eventhough it is JiffyDOS's fault, I intent to make my editors usable with it, as it became pretty much the de facto standard for c64 mass storage file transfer.
The status bar works pretty much the same as in earlier engines. Except you can give your cave name up to 14 chars, and some values got an extra digit for more flexibility.
If you want to use the older PLCK engine, you would probably use Deluxe Packer 1.51:

It is completely in English and has a manual (the English one is on the disk). You can use your graphics set and you can change your text char set, but you can't design a big title screen with big letters with it. You have always a top ten list on it and only a few lines to design your title on.
