dub can't read files from cache

[Ruslan via Digitalmars-d-learn]

My first experience in D programming. I've already installed dmd2 
and dub. I init new package, build and run it using dub - it 
works properly. Then I insert:

"dependencies": {
		"dfl": ">=0.0.1"
	}

to dub.json file. Dub fetch "dfl-0.0.1" , but can't read after. 
Build command gives:

app: ["app", "dfl"]
Building dfl configuration "library", build type debug.
Running dmd...
Error: cannot read file 
..\Users\╨а╤Г╤Б╨╗╨░╨╜\AppData\Roaming\dub\packages\dfl-0
.0.1\source\dfl\all.d

Please help. Thanks in advance.
