Rainy, I am with snowman. I have been running Rainlendar 2.3 b59 on Mac OS X 10.5.3 for a couple of weeks now and it all runs great! If I buy and register Rainlendar, can I use that registration with the Mac version of Rainlendar and will it remove the [UNREGISTERED] tabs from my Google calendar items?
Thanks,
Serpentor

Yes, the license files work in the Mac version too.

I've the same problem. I've use Rainlendar before, the program is already on this computer before I use it. Then I download the lite version (2.10-32bit) this morning, and found warning msg everytime I try to running the program (the program can still running but will always have this warning msg before).

I'm not sure what the problem is, but before I'm running the program this morning, first I'm installing some Rainlendar skins, one of them detected by antivirus have trojan on it.

Welcome to the forum, rapaelh.
Then I download the lite version (2.10-32bit) this morning, and found warning msg everytime I try to running the program (the program can still running but will always have this warning msg before). It's not bugs, it's because you download Lite version, it not support Network Calendar and Outlook.
You can do this :
1) Ignore the warning message and continue to use the Lite.
2) Delete them from "C:\Program Files\Rainlendar2\plugins\" and continue to use the Lite.
3) Download and use the Pro version.
