aMule big trouble

I used aMule since I bought the nas drive without any problem, but 2 weeks ago I decided to reset my device with a complete restorarion, format my drive and install again aMule and configure it. Everything was going ok, fast download, but, when the file reaches 100% aMule lost servers, can’t convert the .part files into the proper file I am downloading and finally stops working until I reset the MyCloud device. I restored everything again but the trouble persists, and I´m becoming a bit mad trying things, maybe it´s a permissions trouble but i´m not an expert on this things, does anyone have the same troubles?? Can someone give me an idea of what i´m experimenting?? Thanks
