Hi, 
Hopefully this works, because my posts will need approval. But, If it is not approved, I get nothing as reply. 
I want to use kACARS as my PiREP-tool. Unfortunately I get this *** error again and again. Everything I tried will return this error. I am using HostDeal (hostdeal.eu), but they can't figure it out as well. And, yes, it is a paid host. 
Which error do I get? 
Notify System Administrator of the Switch error. 
Data not received 
Switch = verify. 
Now I have 2 core/module/kACARS_FREE. One in my public_html and one in my public_html/phpvms. I sure want to register and pay, but if this doesn't work, the paid version will not work either, I believe. 
Hopefully you can (finally) help me! 
Kind regards, 
Stefan (Maanlander).
