new groups and contacts in. those groups disapear

Today I logged in and about 6 groups I recently (within the last month) created (full of contacts) were no longer there. I logged in and out several times. Sometimes the groups appeared and other times it only showed the groups and contacts I had before I added the new ones last month.

One of the times the new groups DID show up I clicked on it and no contacts appeared, just an error message.

It seems like the datablase must have crashed or been corrupted without me doing anything. Is there any way to give ACT a heads up that their system has bugs? What can I do to make sure I don't lose contacts or notes?
