Donation version gives problems when it is used on more than one computer

[MauriceH]

Hello Zenju,
I use the donation version for 1 year now (I have a donation of 2 years and will continue this). And i'm very happy with the tool. But I use this software on multiple servers. When I update now, I got the error :
Error: FreeFileSync Donation Edition was registered to be used by at most 1 user(s), but was recently activated on 6 different machines.
These machines are from me...
There is never told me that I may not use it on more than 1 machine!!
