Table alias a_065a97880625e1118ea61cc1def13751 is not unique amongst all top-level table and join aliases

Recently we have modified few views in CRM 2011 online. After modifying the views, we were not able to access the view in CRM. Getting the following error message.

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: System.Xml.XmlException: Microsoft Dynamics CRM has experienced an error.
