[Plugin: VoucherPress] Permission issues

I would really like to try use the plugin, because it solves a big issue for us (we would even pay for it, or pay someone to fix this for my company). But it doesn’t work, no matter how the permissions are configured, when we try to create a new Voucher we get the error:

The system was not able to set the right permissions on the folder where your custom templates are stored. You may not be able to upload your own templates. Please contact your system administrator for more information.

Now I Chmoded 777 the entire site, because I wasn’t sure if this was trying to write to a directory outside the plugin, but I still get the same error. I have also made sure that safe_mode was off, which I found out is off by default anyway since we are running PHP5.

I really don’t know what to do short of having a custom plugin built, since any of the other coupons plugins are actual coupon sites, which is a bit overkill for our needs.

If the creator of this plugin could contact me, I am willing to pay you hourly or whatever to get it working on our site.
