Could you please report such problems in the future, cause if you don't report we have no way of fixing it.
I've reported some errors in past, without ever getting any response.
The question is to where you were reporting the problems. If it was to support@farmanager.com then it probably was lost cause that address haven't been working for years, because of large amount of spam. The best place to report the problems nowdays is in the new offial forum. And for problems with API it is best that you provide a simple test plugin with sources.
