Hello
If you are running converter on the machine you want to convert (i.e. 'this local machine' conversion), then the worker log is the place to look. It would be best if you can paste all the lines relevant to that conversion; if not - look for other 'error' and 'warning' level lines. The ones you provide are only warnings (... [01396 warning 'Default'] ...)
If OTOH, you are converting a remote machine, the relevant log is the agent's one. It can be found on the source machine.
