I've been using your module since May and it's been working fine. I noticed that there had been a lot of recent updates so I downloaded and installed the latest version of the module and now Export-Excel is not working at all. Whenever I try to use the module I get the following error. For example:

PS F:\PowerShellScripts> Get-Service | Export-Excel services.xlsx
invoke member w/ expression name
At line:1 char:1
+ Get-Service | Export-Excel services.xlsx
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], NotImplementedExceptio
    + FullyQualifiedErrorId : System.NotImplementedException

I cannot figure this out and don't understand what is happening. The previous version (from 27th May '15) worked fine. It seems to be an issue with the Export-Excel.ps1 file, which didn't even exist in the previous version. I also noticed that parameter completion is no longer working for the Export-Excel cmdlet.

I am using PowerShell 3.0 on Windows 2008 R2. I also tested on Windows 7 with PowerShell 3 - same issue. Reverting back to the previous version works fine.

Hope you can help!
