Hi Guys, My database is working great until today. I followed the video on how to split and trust a folder in our fileserver. After splitting it, it worked really good. Today only one thing wasn't working but on my other copy it was. I had to remove the split one and had to do a whole split on my backup. I then tried to log into it but it wouldn't let me. I finally after several hours made a new access database and moved all the tables, queries, forms etc into the new one. Now it shows a compile error user defined type not defined. I need help to understand what that means. I am watching the troubleshooting videos.
