Greetings from Colombia
Thanks for your kind and rapid answer, I have already updated the system on my computer and on a server that we are using but the error still appears. What do you think we should do to solve this?
I've just posted a new version (2020.1.64). It fixes a range error when using forecasting expressions which may be the cause of the problem you are seeing. You can download here: https://leap.sei.org/download.
