I left JForex open over last weekend - it didn't do anything, was just open. Didn't even loose the connection.

Today (Monday) I wanted to compile one of my strategies which I tested last Friday and suddenly I get "tons" of compilation errors about inability to resolve any of the JForex types/symbols (like IEngine etc.). It looks like the application lost its libraries while doing nothing....

Second problem is when I try to create new strategy - this is what I get in my Java console:
