Okay I feel like an idiot but I cannot for the life of me figure out how to get sector maps for VRC.  I have just recently discovered VATSIM and decided that I would like to learn how to be an ATC.  I haven't taken any exams yet but I was really wanting to just observe in VRC to get a feet of what to expect.  I went to your training center and followed the instructions to observe in VRC. It referenced me to download the maps from the VATUSA website which I attempted to do.  I was trying to acquire the maps for KMCI or KSTL.  I searched using those codes, found the airports and began to individually download each pdf.  After which I copied them all into a subfolder into the VRC folder. I then went to File, Open Sector and low and behold the program doesn't recognize the pdf's. What am I doing wrong? I am so confused.  Any help would be GREATLY appreciated.
