Yes, same error code in Croatia. Must be marketplace error.
There was an update from 7.5 on 7.8. However, update is not possible over marketplace, you have to upload it over Zune.
Hi, I have the same issue on my Lumia 800. I cannot install apps from the Market Place today neither via Wifi and 3G. Yesterday was everything fine. I think it is a Microsoft Problem.
Same in India also. I was using this phone for a week and while downloading any application Error code 805a0193 is displayed from today.
Try restarting the phone. It's working fine again for me..
