Wont open anymore

Ive had this app since the summer since I was working a doctor and was using it to see certain mechanisms for drugs he was prescribing. Id like to keep using it for my pharmacology class but the app wont open anymore/it crashes as soon as I try and load it. Ive tried reinstalling it but that did not work. I dont know if any other users have had this problem, but if so, please fix! Im currently using an iPad mini with the most updated software, too.
