Cubik Pro 1.8: 1st Person Model, Dropped Items Issue, Textures Issue [Solved]

[Reduce_]

After designing my textures and putting them in the correct view for a 1st person model, the in game version is always different from the one shown in Cubik Pro. In the pictures attached (last 2), the texture for the gun is aligned to the edge of the screen. However, in game, it isn't. I'm not sure if this has to do with screen resolutions or anything, but I'm currently running at 1920x1200.
Also, dropped items don't change at all. This issue is for 1.8.0 only, and does not include 1.8.8, etc. Is there any way to fix it?
I'm currently using the 1.8 version of Cubik Pro (Version 0.95 Beta).
The first picture shows the texture put in Cubik, and it has these weird stripes. Doesn't show up when in Minecraft, but extremely annoying when editing the views.
Thanks for any help!

Cubik Pro is no longer supported

Is 1.8 not supported anymore for textures?
Will you be releasing a new version for 1.8 sometime later? Many people still work in version 1.8, and just using the old program results in many bugs...

I did manage to fix some issues myself- the one with placing the image towards the edge and not showing at the edge can be fixed by making the program full screen.

Decrease your "Field of View" that should fix the problem.

As for 1.8, which is the version I tested it on, FOV has nothing to do with the items in your hand. It only changes the surroundings; if you were on Quake Pro items would look stretched out, and that isn't the case.

I did manage to solve it, though. In the post ^^, I mentioned that the Cubik had to be full screened in order for 1st person items to be put in the right place.
If you make the Cubik smaller, it somehow makes the items move slightly to the left. Probably a scaling issue they didn't notice.
Thanks for the recommendation, though!
