LINQPad 4 Error in Downloading More Samples

I am having this error when I try to download LINQPad sample libraries: Error while unpacking sample queries: C:\Documents and Settings[user]\Local Settings\Temp\LINQPad\TempSampleQueries849247.zip i开发者_JS百科s not a valid zip file.

I use LinqPad 4 (installed version). The weird thing is I also have LINQPad 4 (licensed standalone executable) at home and I didn't encounter any problems in downloading. Do I need to have license to be able to download the sample files?

Edit:

I am also having problems in activating my LINQPad. The error says: Unable to contact licensing server: The remote server returned an error: (407) Proxy Authentication Required. I pretty much sure I'm not using any proxies. Please help! Thanks.

Are you certain you're not going through a proxy? I don't see any other way you could be getting a 407 error. Entering the proxy username/password into LINQPad's proxy dialog (Edit | Preferences | Updates) should fix it.

If you're still unable to proceed, you can perform an offline activation here and download the sample libraries via a web browser here. After downloading a samples zip file, click 'Download more samples' and type in the local file path to import it.

Simple solution to prevent the proxy 407 authentication needed error when licensing or updating Linqpad: Add the following to Linqpad's config file

<system.net>
    <defaultProxy useDefaultCredentials="true" />
</system.net>
