What could it be because of?

Does this happen on the same machine that you logged into the website from?

Yes. Now i can into Reactions BETA. But if i want see some presset, as soon as it opens with all its settings, the program crashes.

Please try Build v0.2.0-28, there have already been a few bugfixes since the v0.2.0 release.

The login problem probably was a regular network connection issue.
