Hoster 2.212 Import track problem

[is14fun]

After installing new upgrade, I cannot seem to be able to import any new tracks to my database. Each time I try I get the a error message saying the disk id number I have used is being used by another disk. I know that is not possible as I have deleted number 75 from my database and rebuildt my hoster data file. The pull down menue on Brand ID and Disk Id are all empty so the problem must be with this but I don't know what I should do to fix. I have 74 disks in the database and the program does recognize them when I do a search.
