Hello, 

I have contacted the professor of EE688 in order to audit his lecture. 

Professor accepted and added me to KLMS. I was able to see the lecture materials in KLMS, but then it disappeared. 

Thus, I contacted the professor again and he added me once me yesterday. Again, I was able to see the lecture materials yesterday, but then this morning, it disappeared again. 

I feel embarrassed to contact and bother the professor again because he already added me twice. 

Could you please explain what happened and how to solve the problem? 

Thank you!

Regards,

Toumadher
