Meetings created in ACT - disappear and then reappear

[crazywriter]

Recent Problem: We logon to ACT, enter and update meetings, todo list etc and logout.  Login again later in day and database has dropped all kinds of information, not just the most recently added data.  Then we logon again a couple hours later and the data is back where its supposed to be.

Yesterday, I tried restoring from a previous days backup but this morning whole sections of the past history has disappeared again.

Has anyone had this experience or have any ideas on what is happening and how we can stop this?

Thanks

Does this happen for all users?

I'd start with a database repair as per this ACT! Knowledge Base article -
