I reinstalled PlasticSCM and tried again.
Just in case, when uninstalling, it is installed after manually deleting the following folders.
AppData \ Local \ plastic4
Program Files \ PlasticSCM5
After repeating steps 1-9 for about 40 minutes, an error occurred.
The 3-4 repetition I wrote in the previous reply were few.
I'm used to the operation, so I'm doing steps 1-9 fairly quickly.
and I have generated a lot of conflicts.
It's scary because it's an unexplained error, but it may happen less often during development.
If the cause of the error is resolved in the future, I would like an announcement or reply.
thank you.
