With the current v4 you will have to copy the whole c:\easisldies folder before you can use a worship list you had prepared on another PC. This is because easislides uses internal database unique IDs to reference songs, and the easislides database on different machines will use different song IDs, hence it won’t find the right lyrics.
With v5beta, internal IDs have been removed. All lyrics are now identified by:-
1. The lyrics database name
2. The lyrics title
3. The lyrics author
All easyslides database songs you saved on a worship list will use the above information. The worship list is saved within your user documents folder at EasySlidesData\Admin\WorshipLists\. You can copy the appropriate worship list to the same location in your destination easyslides PC. When easyslides uses that worship list, it will look up the correct lyrics on the destination pc if it has the same lyrics database name, lyrics title and lyrics author for each item.
