Crashing ALL THE TIME!!!

Adobe Digital Editions is constantly crashing on me. I need to use ADE for digital versions of the textbooks I use in university, and my highlighting and notes disappear whenever the system crashes so I constantly lose all my markup. I know the simplest solution is just using the paper books, but they are all so heavy to carry back and forth, so I liked having everything on my laptop. I know this is something Adobe just has to fix, but does anyone by chance have the same problem or any solutions? It's driving me nuts because the only platform I can use for my books is ADE.
