Connection NOT established Ifix 5.8

Hi to everyone.

I have one big problem, i do all the development for the Ifix in Ifix 5.8 demo mode because i don't have the respective license for that, i just have the license for the runtime environment.
The problem is when you put in runtime in demo mode all the parts of the program works pretty good, but when i put the license for the runtime, 5 or 6 seconds after, the Ifix lost the connection with the IGS and all my values going to communication error(@@@@@).
The license that i have is for the Runtime in bundle with the IGS drive, with an unlimited number of tags for work between this two.
I tried lot of things and no one work.

Any idea??
