Management Panel Black Screen no access

[D_O_B]

OS Name/Version: Windows 10 Pro Build 19045

Product Name/Version: V2.5.0.12

Problem Description: After updating from V2.5.0.10 to V2.5.0.10 Management panel does not come up other than a black screen . I upgraded in hopes that my DayZ server would work again as it did with the previous edition of AMP . Other servers worked fine after the update to V2.5.0.10 but DayZ would not start . Then updated to V2.5.0.12

Steps to reproduce:

 * Step 1  Start AMP after reboot tired to access manager .
 * Step 2 Reinstalled AMP in  repair mode .
 * Step 3

Actions taken to resolve so far:
Followed the guide precisely for updating AMP , Reinstalled AMP in repair mode . Upgraded each instance individually tried to access manager and all I have is a black screen  on all instances. 
Willing to try just about anything but cannot loose data on one server out of six , an enshrouded server my mates have put to many hours into building. 
At this point I am concerned about my backups for this server .

Thanks

Same issue, I’ve tried upgrading the individual instances, rebooting it all, running the admin instance manager to no avail and can’t figure out how to roll back updates

I FIGURED IT OUT. whatever web browser you’re using like chrome for example. i use chrome, clear the cache out and it’ll work
