You'll see the two ini files which are the English ones with date modified in 2012. I haven't fixed all the spelling mistakes but relabelled most things according to my twisted version of what I call logic. You can play with the files and keep your originals under a different name to restore when you want.

Not sure how I can post a non-image attachment, but if you want them PM me with an email address.

Note you'll have two copies of Laserwork on your hard drive, even if you "plug laserwork" as I did following your advice. One in the C drive (or your root) and one in the location I show above.
