I had a DC Pro account for several years. It always worked fine (iMac Catalina). I let the subscription lapse. A month later, I renewed (same iMac but Big Sur). Today I opened a contract that I had created under the old subscription. I used Fill/Sign to add some text in several locations. When I got to one spot in the contract, as soon as I clicked where I wanted to add someone's name, I immediately got the Beach Ball of Death. The program froze and eventually crashed. Subsequent attempts produced the same result. I Forced Quit. I uninstalled and re-installed with the same outcome. I have no idea what is going on and don't know what to try next. Any ideas would be appreciated.
