Robby,
When Lee suggested going to the back of the tent and collecting the Sniper Rifle and taking a screen shot - your images attached do not show that location at the back of the tent?
Can you grab a screen shot of the Table at the back of the tent where the Rifle should be seen? Does the Sniper rifle exist (show up) there at all?
If not have you tried placing (adding ) a new weapon and check to see if it firstly displays and can be seen in the editor window. If you can see it in the editor then that's a start. It should therefore be in the level when you test run it so you can physically see it and collect it.
If you cant see a weapon placed in editor then clearly its unlikely to actually be physically being loaded/created at all.
I would suggest that if that is unsuccessful in helping then you could try starting from scratch by creating a simple Flat Terrain Level. Add a player start marker. Then add a weapon in editor. In fact try adding one of all types of available weapons and see if any of them actually show up in editor. (presuming they all in fact exist in the weapons folder). Make sure all the weapons are placed somewhere near the player where you can easily find them in the level.
When placing weapons - zoom in closely so you can see easily find/see them and make sure they are placed above ground (terrain level).
Add one other object like a simple static box as a marker if you like so you know where the weapons should be approximately. Place one on top of the box also may be a good idea so it cant fall below the terrain.
Lastly does the player have a weapon attached to himself to start the level. If not try editing the player marker (right click in editor) and give the player a weapon to start the level with.
Now having said all that if you cant actually see any weapons in the editor window when you place them in your level then the rest I guess is of little use of course as clearly the weapons are not being found/loaded/displaying by Reloaded at all so I cant help there at all I am afraid. (presuming of course as said they do exist in the Reloaded install directories?)
Presumably you may already have done all of that? Have you tried deleting all the .dbo and .bin files from the entities weapons directory location? If not that may help - exit/shut down Reloaded first if you try that and make sure you make a backup of the said weapons folder before deleting anything or don't do it at all.
