If I try those search terms from my end, I also get a 'Page cannot be displayed' from my end. :rolleyes:
Interestingly, this only seems to happen if common keywords are entered. For example, if I search for 'Scratches' or 'Handling' (or both keywords), I get results. However, if I add the keyword 'Error' or 'DVD' (or both) along with the other two keywords (or even on their own), I get a 'Page cannot be displayed'. This also applies with certain other common keywords, such as 'Software', 'Burning', 'Nero', etc.
For now, try one keyword at a time to see which returns results and then enter the keywords that work. For example, in the above scenario, try "scratches handling", however unfortunately until this issue is resolved, there is no way of narrowing down your saerch unless you can find substitute keywords to those that give the error.
