ADE 4.5 stops working when I attempt to copy text from the ebook

Hello everyone. I have been using ADE for the past few months for school.

Recently, ADE has crashed every time I have attempted to copy something, whether pressing ctrl + c, or right-clicking and copying text. I get a message that states that "ADE has stopped working...Windows will attempt to find a solution to this problem" or something to that extent.

The text is not saved after it crashes.

I can open ADE, and did not have this problem beforehand. I have tried a few solutions involving renaming or deleting certain files/folders, but nothing has helped.

I am using these books for law school, and copying would make my readings easier. Please let me know if you have a solution. Thank you.
