So I did the rename, but it says I already have a file in the same location called "level.dat", so it's now called "level (2).dat", is that a problem?

Спасибо огромное!!! У меня на карте было куча часов, потом пк завис. Я его перезагрузил и выдало эту ошибку. Сделал как тут и даже прогресс не пропал))
