OSCam Manager v1.0.3 for WeTek Play 2

Hello, i have problems on oscam. I installed OSCAM 1.0.3 and work fine, but the locked channels block several times. I try install 1.0.2 version but it's the same problem. Install again 1.0.3 and, in the configuration page, always appears the same version (see the attachment).

Yesterday, i try install OScam Android 4.1 From wetektr.com, but this .apk don't create any path on /sdcard/Android/data, so doesn't work. To resolve, i create the path manually (/sdcard/Android/data/update) and paste the file oscam-EMU-11384.zip to the update path (i renamed the oscam-EMU-11384.zip to arm-oscam.zip). I opened the oscam program and update the file. Last, i configured the reader but any locked channel doesn't work.

Back to OSCAM 1.0.3 and it's work, but with the first problem (block any time).

why no file visible ?

This Oscam working on my WP2, with this ver. of manager, Oscam is 11273, How can I update it to latest or 11390 ?

How use Softcam with that Oscam manager, and, where to put Softcam ?
