LogMeInHamachi Network

I had to reset my PC because my computer was too slow and I didn't delete my networks and stuff. 
After I reset my pc I re-downloaded LogmeinHamachi and I logged back in and I couldn't find any of my before networks and I went to the website to delete the networks and it didn't work. I tried to create my existing network that I created before but it told me that the name already existed and I couldn't create it. 
is there a way to delete it or somehow retrieve it? my friends are still in there and they see me online too but I couldn't see it myself.
