Basically you are correct. CS 4-5-6k receivers are officially no longer supported for the past 6 months-1 year, when they were discontinued by Cooolsat. Ocassionally someone will release a new file, but don't count on it, or expect it to last long with the weekly ECM's against piracy.
Your options are obvious, you need to get another receiver that has good software support. I recommend one also that has USB capabilities for easy loading, and no need to continually disconnect and reconnect cables or move receiver to your computer. I recommend a Sonicview 360 model ( either the Premier single tuner PVR or the dual tuner PVR Elite, dual tuner allows you to record while watching another channel ). Both of these also have multiple USB ports. A honest good reputable dealer is Scott at www.southcoastfta.com , who supports many FTA forums sites.
throw that cool**sat in the dumpster when you get to work thats what i did.i bought 2 cheap pansat 2500 on ebay for 40 bucks works great too.i dont think its work buying a expensive receiver right now unless your rich.
Free shipping is NOT important. Whats important is that you receive the product, its NOT defective, is NOT a clone (fake), and the dealer/seller will back up the product and warranty. Buying at the cheapest place is NOT the best thing or MOST important.
