DO NOT reinstall.
The program is stable (unlike many) and the problem is probably NOT CSB itself.
Generally, you should not have to adjust the publishing settings in CSB, UNLESS:
- YOU have changed your password for the account
- your HOST moved the account to a different server (case sensitive, address change, etc)
- your HOST changed the ftp settings for security, etc.
- your HOST changed the folder layout and now requires different ftp folder
- you MOVE to another HOST.
