Защо получавам грешка "невалидни стойности" при опит за достъп до мрежовите настройки на Eclipse Mars? - затъмнение, затъмнение-Марс

Опитах се да вляза в пазара на затъмнение и не успя, затова отидох да проверя настройките за свързване в мрежа и получих следното:

Ако продължа разделът "Мрежови връзки", не се зарежда отначало, но след като го изключим и върху него мога да го зареди, но Active Provider е празен:

Опитах да рестартирам Eclipse, получих същата грешка.

Отидох до workspace.metadata папка и отвори .log файл, където намерих следното:

Някой знае ли начин да се определи или просто да се работи по този проблем? Независимо дали става дума за хакване на конфигурационните файлове на Eclipse или нещо, което нямам нищо против - просто трябва да се запише отново в Eclipse!

Следвайки съветите тук Аз бях избягал със затъмнението ми eclipse -clean и прозорецът с имоти се отвори добре и можех да вляза в пазара. Рестартирах затъмнението и всичко все още върши работа, така че изглежда, че е решил проблема.
