games not working?

Hi all.Downloaded a few more games for my son last night and this morning, been using Romulation for a long while now with no problems.
Now the problem is that I extract the zip file and then transfer the NDS file to a 4gb micro card as per normal, running TTDS card BTW and all of the files when opening them with the DSi come up with file failure code 7??I have had this a few times in the past but it just seems strange that I downloaded 6 games some of which are duplicated so done them all and they all are faulty.
Is it me or just the download ?
Many thanks.

Think I have just solved the problem,
I have just updated the TTDS program, TBH I didnt realise that they were updated ::)
