Puzzling NAS question

[donkeydru]

Hi guys,
Loving Mezzmo however I have encountered a really frustrating issue recently, I will try to keep it simple and to the point:

I run windows 7 (with mezzmo duh)
Samsung S5 with the mezzmo app
2 NAS, 1 is a seagate black armor business NAS and the other a much older Netgear Stora.
Streaming to Chromecast

Recently removed password from Windows account (only account on the computer).
Sometime soon after lost the ability to browse the Stora folders. The BA NAS still works fine.
To go into detail, all files are still viewable via the mezzmo PC app, however with the android app it just loads for about half a second then nothing, no files, even though the root folders are visible, the subfolders are not.
BA NAS loads fine and PC files load fine.

I have read about the NAS credentials and the tick box thingy in the services menu, done all that and even uninstalled and re installed, re applied password, EVERYTHING. Cant get the damn thing to work.

On a side note, with the BA NAS I add the single root folder and it doesn't display that NAS warning message, however when I add the Stora folders, it does display the warning.
There are other niggling issues related to mounting the network folders but I know that if I get this sorted then it will work, I don't want to confuse the issue.

TIA.
