[Gretl-users] Gretl suddenly closes

Good evening, My name is Petru and I'm starting to use Gretl for the first time, attending an introductory course to Econometrics. I have found some problems when trying to use Gretl, version 2020d for MS Windows (x64 bit). When I tried the first time to download the data files used in Stock-Watson book Introduction to Econometrics from the server, as indicated by my lecturer (File --> Open data --> Sample file... --> Look on server), I have run into a bug that suddenly closes Gretl when clicking install without the possibility to save the work done till that moment. I ran into the same problem also when trying to open any of the PDF help files. I have already deleted and redownloaded Gretl but the problem continues. I will be really grateful if I can have some indications about how to solve this problem. Petru Calenici
