Zainstaluj Javę 1.7. Minecraft nie wspiera w pełni Javy 1.8 obecnie.

[Gość]

Spróbuj usunąć całego Forge z folderu ''versions'' i pobierz odnowa. Drugą opcję wymienił kolega na górze. 

Odpisz, gdy to już zrobisz i daj znać. 

[Marine1001]

Zainstaluj Starą Wersje Javy 1.6 to pomoże miałem tak samo i to zrobiłem bo poradzili na angielskich forach

Forge na 1.7 nie wystartuje z javą 8.

Pobierz Java 7 Update 67. (najlepiej spełnia rolę)

Pamiętaj, żeby odinstalować 8.
