Internal Progam error 58.w.fi.nd

[Riftvalley]

Hi,

I just set up a simple site and got the following message wehn I tried to upload:-
Internal Progam error 58.w.fi.nd

Anyone any ideas please, not sure how to proceed (other that to use Dreamweaver to upload the files, site works fine locally!).

Apologises, should have said that I am using XWD6, on Windows 7 64-bit Home Premium, 4GBmemory. DirectX 10, 2Tb Hard discs,
Quad Core @2.5GHz.

I have uploaded before (different website) with no problems.

Kind regards

Martin
