In general, it is considered a good idea to provide necessary information:

1) Which version of MySQL,
2) exact comnmand(s) used,
3) exact error message text,
4) which operating system.

From you description, I strongly suppose it is a permission problem,
probably the files copied among the "friends" end up with a different
ownership or access rights than those of the original installation.
