Caw FAQ's........Links to Tutorials, and Resources. Textures, & Troubleshooting

Sorry to bother you again. But I was working on my world in edit in game about 2-3 times and have not gone into CAW since EIG. When I go to load up my world in CAW I notice that there is not a Visual Studio Setting icon under it (i think my world had one) but I go to try to open up my world but it wont let me.

It says: unable to load world...........cannot load file...........
I have no clue why this happend
thanks for helping :-)
