Error message when try to save in designer

Hi all!

I am having error message when try to either save chages to a project or create a new one. The message is a problem with writing to a db. It is like that:

[code]GatewayException: Executing INSERT INTO PROJECT_CHANGES (PROJECT_CHANGES_ID, ProjectId, EditCount, EditType, UserName, CommitMessage, EditDate) VALUES (?, ?, ?, ?, ?, ?, ?) for [ProjectChangeRecord 8633 NewRecord Dirty1]
caused by SException$Jdbc: Executing INSERT INTO PROJECT_CHANGES (PROJECT_CHANGES_ID, ProjectId, EditCount, EditType, UserName, CommitMessage, EditDate) VALUES (?, ?, ?, ?, ?, ?, ?) for [ProjectChangeRecord 8633 NewRecord Dirty1]
