OpenGL failure in Texture class

[MGN001]

I'm writing a game using Visual Studio 2012, and when I load the images for my Player class, I get 2 errors per file:

"An internal OpenGL call failed in Texture.cpp<#> : GL_INVALID_ENUM, an unacceptable value has been specified for an enumerated argument"

The numbers that appear in place of # are 146 and 147.

Show us the code you used and exactly where your debugger said the error occurred.
