Unable to load NinjaTrader vendor dll

[bsdzuk]

Hi

I have just downloaded NT 7.0.1013 and having trouble starting the app. The error I get is: -

Unable to load NinjaTrader vendor dll. Please re-install NinjaTrader: Could not load file or assembly 'NinjaTrader.Vendor, Version=7.0.1000.13, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

The logfile has something similar: -

I've tried repairing and uninstalling-deleting-folders-in-programfiles-and-my-docs-then-reinstalling but nothing helps. I am running on Windows 7 Professional 64 bit.

Any help appreciated.
Thanks
