I tried many times in different days to comfort-update to Versión 2.05+ (150413) (stable) from version 2.05RC7 Build 131125 and I got this error at the first step:
Error : PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
Should I check permissions or wait until update server responds? Is there any way to avoid manual update?
