I don't know if you already solved this issue or not but usually there shouldn't be a problem loading projects on another machine.
When you say "move" did you meant that literally ?
Because in that case, you might want to try the publish option on your original machine, and move the results from that over to your other lazarus.
There is always the possibility that the lazarus you are moving your projects to does not have the required components installed but in that case i usually get lazarus to display an error message telling me that and if i want to remove the (invalid) declaration(s) or ignore (them).
Either way, you would at least know what component is causing the issue as streaming errors should be displayed/presented.
I am not aware of any logfile, unless lazarus itself is compiled with debugging.
