Toad for SQL Trial version get an exception when tables tab is selected

I installed Toad for SQL trial version successfully. The program works as expected but, suddenly it began to got an exception when the TABLES tab is selected.

The error is:

System.IndexOutOfRangeException
Index was outside the bounds of the array.
Stack Trace:

Server stack trace:
at Quest.Toad.Trl.SimpleExtraColumn.GetColumnValue(ITrl trl, FastRow row, Int32 currentExtraColumnIndex)
at Quest.Toad.Trl.BaseSqlTrl.AssignExtraColumn(FastRow row, ITrl trl)
at Quest.Toad.Trl.SqlTrl.FilterToTrls(FilterInfo info, FastTable table, Boolean bSorted, Int32 offset, Int32 maxCount)
at Quest.Toad.Trl.SqlTrl.GetFilteredTrls(FilterInfo info)
at Quest.Toad.DatabaseBrowser.ObjectPaletteControl.ReadTrl(ITrl trl, Boolean& displayExpandIndicator)

It is not a SQL issue since I am able to open it when other tools.

Any help?
