Do you think it could be becaus I did not uninstall diving log 3.0
No, version 4.0 can be without problems on the same computer as version 3.0 installed. The problem on your system seems to be clicking on the AdvPic control, and the only functions in Diving Log are the flag picture, the brevet pictures and the help button, so you shouldn't click on this until we find a solution.
Where is the server?
Yes the server is in Europe, but I think the forum always display GMT time by default, and you must tell the forum where you are (in the profile settings).
I started it from the Menu bar ade is working but is only available in german version.
Normally nothing should appear, because the help file of version 4.0 isn't finish at the moment. What you see is the help file of version 3.0. Do you installed version 4.0 into the same folder as version 3.0? Maybe this is the problem. I suggest you uninstall version 3.0 and 4.0, download the newest setup from the website and install this again. Maybe then problems are solved.
I did set time zone to GMT+1 but this is not so important.Thanks for the help for now and I hope you find a solution for my problem soon. I hope I am not buging you with many questions.
As I said yesterday I unistalled 3.0 and 4.0 and installed just 4.0 and registered it but still can˝t import from aladin. ( Error number : 3421 )
Those buttons are still stoping diving log as well.
