Same here. Cakewalk opened one day, the next day when trying to open CWbBL, "Windows has encountered a problem" message comes up while Cakwalk mast head hangs and only option is to shut it down. I did do a windows update the day before yesterday but ran CWBBL after with no issues. Uninstalled, reinstalled, COMPLETE uninstall, clean install...same problem.
I also installed a legacy version of Sonar Professional from the old Control Center and it runs fine albeit without the quality of the newer CWBBL.
Bandlabs wants me to pay for this?
I also downloaded and installed/tried to run Cakewalk Product Center and it won't even run.
