I took the course in French a long while ago. It wasn't that difficult to follow except perhaps some of the discussions about someone's particular business venture (and I don't think it was compulsory back then).
Many services for foreigners have been cut back over the last 5 years to save money (free French lessons, courses in English and so on) and it's now very similar to the situation 15 years ago - i.e. nothing special is laid on and TBH, this is probably best.
To be certain that it is no longer an option you should ask at the Chambre de Commerce in Guéret. They are (mostly) helpful.
