I just bought a zenithink 180 in November. I didn't have problems and i didn't use it for a couple weeks, when i went to turn it on it keeps saying to wipe out the data. now it wont recognized my movements when im touching the tablet. almost like its frozen, but if i touch the home buttom it will detect that. I am trying to upgrade the software and i need to use my lap top because my computer is 64 bit. Any suggestions?
