Greetings Andrei!?,
I'm having re-registration problems too! At last moved from XP! Only up to Windows 7! Reg key works with v5.0.0, but when I upgrade to v6.5.4, it asks me to register, again... And cannot read dab file on 5.0.0, so... can you help me?
Updating...:"Found out that after v6 it uses a different licensing scheme. The new version should automaticaly ugrade it, through some kind of web server connection. Problem seems that v6.5.7..., at least, doesn't do that anymore. So I've found v6.4.7 (I did keep some previous versions, just in case!), upgraded with that one first, them with the last version and all went well!
Anybody needing to do that, and not having a v6.4.... version knows now where and whom to ask! (Not wanting to surpass Andrei!)"
