Delete\system\apps\putty\defaults

Sometimes Putty may fail to start because the default configuration file is corrupted. The simplest to fix this problem is just delete that file which is located in \system\apps\putty\defaults , on the drive where Putty was installed.

If this helps nd you can figure out what you did when the configuration file get corrupted , please file a new bug report with instructions on how to reproduce a the problem.......
