problem to install tar games

Hello ,after a fresh vb and ibproarcade install i tried to load my "old" games, but he doesntwant to install any (!!) tar file. By the zips are not so massive problems but by the tars he allways say:

Error in TAR-Archive. Please upload again.

I tried to upload as hexadecimal, also in binar mode, but no solution. Any hint?
PS.: I downloaded from ibparcade a few (tar) games, tried to install it, but become the same result.
