Can't create a report

[almor]

Hello,

i'm trying to create a custom report in FF
So, i open a report builder and paste my query at the bottom of the page.
In the middle of a page i see a message "Query is changed, need to be updated"

But the table on the top not appeared and when i try to save it, i get an error:

"Error during saving: "ExecuteReader: CommandText property has not been initialized""

Here is my query:

Select Top 1000000 dbo.tblAssets.AssetID,
  dbo.tblAssets.AssetUnique,
  dbo.tblAssets.Domain,
  dbo.tsysOS.OSname,
  dbo.tsysOS.Image As icon,
  tblFileVersions.FilePathfull,
  tblFileVersions.FileVersion
  From tblAssets
  Left Outer Join tblFileVersions On tblAssets.AssetID = tblFileVersions.AssetID,
  Inner Join tblFileVersions On tblAssets.AssetID = tblFileVersions.AssetID
  Inner Join tblAssetCustom On tblAssets.AssetID = tblAssetCustom.AssetID
  Inner Join tsysOS On tsysOS.OScode = tblAssets.OScode
Where tblFileVersions.FilePathfull Like '%acrobat.exe' And
  tblFileVersions.Found like 'True'
Order By tblFileVersions.Lastchanged Desc

Also, when delete an existing report, i've get an error, but report is deleted successfully :

Erreur du serveur dans l'application '/'.
La ressource est introuvable.

I'm using FF 18, IE9 and last Lansweeper 5039
