CHIRP

Dear all,
I have 3 pofung F17 (PMR446), but I'm experiencing a lot of issue in setting. The CPS downloaded from their site (http://www.pofung.cn/download.asp?EnBigClassName=CPS%20software) is actually named T11 but it doesn't work.
When writing to the radio (even if the success pop up appear) there is no any data saved and if you read again from the radio there is no data available.
On one radio I have been to save data with their CPS_BF-88EU_PMR446 V1.0 (with some issue like the channel start from 2 instead of 1). On the second radio it doesn't work, on the third one basically I have now the radio always in receinving mode (like squelch) so I can't no longer connect.
Can anyone help me? I'd like to completely reset the radios and start with CHIRP.
Thanks
