[Xposed Framework Modules] l3enjamin:
I have been using version 1.4.8 for a long time and yesterday I purchased the market version to support you. However, the market version FC. I have tried to install the previous versions and find the last working version is 1.4.9.

I have also tried to uninstall the app then install it again but it didn't work, so I tried to investigate the issue by using logcat. The following is my logcat output:

Seems that the app is unable to remount the system to /rw. I am sure that my phone is rooted, and other apps that required system rw are working (as well as this app before ver 1.5.0).

I saw some other users have the same issue in this thread too. Can you please look into the issue?
