A common problem is that Pokemon Go, after capturing the first creature, the map is empty, and we can not play. That is, it is neither possible to capture Pokémon or perform other actions. The error is widespread, and to have no solution.
Interestingly, the failure to see Pokémon on the map affects Latin America, or at least to many users in the region. Everything indicates that this is a restriction, we assume that temporary, creators of Pokemon Go. So there is no alternative but to wait for an update.
