First off, you should create a new thread for each question instead of re-using your old thread. You should also give your thread a descriptive name instead of "two issues" which says nothing about your problem at all.

As for your level problem, you have to remember to re-attach/include your main script to your copied levels so that WED knows what folders to add and where to search for the assets. Goto File -> Map Properties to add the main script. Your main script can include PATH bindings to resources. I believe a WDL file can also be used for declaring paths for WED.

If you had been using all assets in the same directory as your original level file, you should be able to copy all the files together and there should be no missing-file errors.
