I bought Arnova 8 tablet and I've been trying for few hours now to find out what is wrong with it. I did everything step by step to download and install Android Market App but nothing seems to work. As I start ArcTools 0.62 and successfully downloaded Default App & Market 3.0.26 (Android 2.2) or/and Default App & Market 2.2.7 (Android 2.2), press Install apps button and then it comes on the display this:

Copying Applications

Error 28: Cannot create temporary directory

Error 20: File copy failed 

I am not a gadget geek and I need some simple explanation how to fix this. There is no SD card inside.

I read quite a lot of information about it but could not find solution to my issue.

Need help!

Thanks!
