I have also problems with Simlink, but also with Navigraph Charts and Simhub. Both on PC and Mac.
1./ Simhub starts up in 5 instances. (I saw that when I used Ctrl Als Del). The instances remain active when I close the program. After that I can start it up, but I do not see the window anymore.
2./ Navigraph charts does start up, but I do not see the window.
3./ Simlink starts up with startup. However it freezes. I can open the window, but after that nothing.
Last saturday I reinstalled everything, It worked, but now it does not anymore today, same problems all over again.
I discovered this because my connection with the Mac suddenly did not work anymore.
1./ Charts asked for Simlink. I could not find it on my system anymore. (I could not remember ever installing it).
2./ I installed Simlink, it could not connect with my simulator, however it seemed to work fine. Chars kept asking for Simlink.
3./ When I reinstalled everything on the PC, it worked fine.
Today I had to login to Simlink all over again. The only think what seems to be working is the connection with Simbrief. I discoved that again there was no connection. When I checked the PC’s software, the same problems where back.
Today I did not reinstal everything on the PC, because I wanted to do a flight without flightplan. But this is not what is supposed to happen, that I have to reinstal everything everytime. So I hope you can help me.
