With the proxy-trick your internet traffic gets re-directed, so the website you are surfing at actually believes you are surfing from the Proxys location. To do this, you need to go in the options menu of your IE. From there you need to find the "connections" tab, where you will find a button called "LAN settings". Then check "Use proxy server for LAN". Now you need to enter the Proxy adress and the port. To find one, you can use google (I found some under
http://tools.rosinstrument.com/proxy/). just click one of the list and you will see a page named "statistics for ip-123-...". Take the IP from there and use dots instead the dashes (So it looks like 123.456.78.90. The Port ist the number just before HTTP, for example 8080. Then close your IE options and goto the store (Beware, your connection is usually very slow now). Then add the game to your cart, choose the PayPal checkout option and when being redirected to the PayPal login Page goto "options" again and uncheck the "Use proxy server for LAN", so you donīt need to send your PayPal account infomation via the unsecure proxy connection. Login in to PayPal, send your payment and use the Impulse downloader to get your game. Worked for me from Germany. Good luck!
