ACCESS DENIED

Hi,

I'm unable to connect to my sharepoint site.
I'm sure I gave the right credentials but I keep getting this error :
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
   at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   at SPCAMLQueryHelper.SPWSLists.Lists.GetListCollection()
   at SPCAMLQueryHelper.WebServiceWork.LoadSitesAndLists.Worker()
I gave the user - pwd - domain. Then I entered my site url, and I had this error when clicking "load" button.
I tried with several admin account, each are AD account.
FBA is also activated on server though. May it be the root of this error ?
