How can I install an older licensed version of R# over an expired Trial version?

I have a license for version 7.X of R#; I use it at home.

At work I've been using the trial version of the latest iteration until it expires. After having it expire a couple of times, I decided to just use the older version for which I have a license at work, too.

I downloaded v 7.1.3 (ReSharperSetup.7.1.3000.2254.msi) from here, and installed it (it seemed to go fine), but when I opened Visual Studio 2013, it gave me the dialog about R# 8.Whatever trial having expired, and there's no Resharper (7.1.3) menu.

How can I install v 7.1.3 now? Or must I revert to using trial versions of 8.Squirch?

UPDATE

My problem appears to be that my license is for version 7.X, which does not support Visual Studio 2013.

So, my options are: purchase an additional license, or continue to use the trial version until it expires, reinstall, rinse, repeat, etc. etc. ad nauseum ad infinitum

UPDATE 2

So I'm in kind of a Catch-22 here; JetBrains has cut me off, apparently, from using another trial version of R#, because I only see "Expired" now on the R# dialog after downloading and installing the trial for version 8 again, and if I try to use my version 7 license:

So, I had to restore the inherent Intellisense via Tools > Options (and [che,ti]cking "Auto List Members" and "Parameter Information)" like so:

Although this doesn't directly solve your particular problem, here's something for those who are just looking for a specific version.

In your scenario I would recommend emailing them and purchasing an upgrade from 7.x to 8.x; It's only $89 for the C# edition if you've already got a personal license to a previous version ($149 for commercial).

There's a list of the archived versions available from the ReSharper website, on the download page:
