Reading Error (No access right)

Hi, I am sorry if this is a double post, but i couldn't find a working solution using the search toolbar on the top right of the forum.
I am fairly new at 3d point clouds analysis. Using an export function of a 3d ToF camera (PMD Pico Monstar) I exported a surface in terms of ply. The ply contains xyz as well as unchar colouds (RGB). However when i tried opening it using cloud compare, i was given an error.

I believe the format of the file is correct, since Cloud compare display this window (figure 1) when attempting to open the ply file.
However it instantly gives me an error (figure 2) after i click apply.I have tried changing the name of the file (makign it shorter, as well at path location) but it didn't help.

Any ideas/suggestions? Thanks!!!

I think the error displayed by CC is misleading but there is indeed an error. The file content is mostly rubbish (you can open it with a standard text editor): most of the points are "0 0 0 4294967288 4294967288 4294967288". Where the 3 first values are 'x y z' and the 3 next ones are 'r g b' which should be between 0 and 255... Therefore the 3rd party library responsible for reading the file returns an error (which CC interprets as a general reading error, which is not the case here).
