Try uploading the files once again.
If it still occurs, use another FTP program.
I recommend WinSCP.

 

[Beermonster]

I've done that and still the same, is there a way to stop it wanting to upgrade while this is fixed?

 

[Paul B]

Try downloading the .zip package again from your customer area.
The one you have may be corrupt.

 

[Beermonster]

I did that before I re-uploaded it

 

[Paul B]

The only times I have seen this it has been due to file corruption, either from the original .zip or during the upload.

If you open a ticket and provide FTP and ACP access I can take a look.

Will do, thanks
