I am getting the same errors when compiling data from J 1.51 w/ EC 2.0 to Compile for 1.0+.
Error deleting ../administrator/components/com_export_content/zip/ import_content_data.zipError deleting ../administrator/components/com_export_content/new_version/ import_content_data.zipError deleting ../administrator/components/com_export_content/new_version/ install.mysql.utf.sqlError deleting ../administrator/components/com_export_content/new_version/ install.mysql.nonutf8.sql

It compiles fine for 1.5, i have also changed permissions on zip to 777...

any ideas, thank you in advance for your help
