Thank you for quick response. After I clicked on the map centering option, maps render fine now. Sadly, I have no WiFi access for the next few days, so I cant access the Locus shop now, but will try once I will have WiFi connection again.
Edit: But is it neccessary to download the cyclohc, when I already downloaded the .zip file via PC, extracted it, and coppied into the phone into the /_themes directory?
