We have a 5510 with IOS 7. I cannot access ASDM GUI. Prompted for user name and password and ASDM window opens, progress builds to 100% and hangs. ASDM Launcher returns nothing. builds to 100%, reads "Update complete", then nothihng comes up. I configured ASDM with the image indicated in flash- asdm-508.bin. Using Java 6 or 1.6. Same results for IE, FF, Chrome, Safari. Also cleared cache in browsers and Java. Zeroised RSA keys, but no good. Tried allowing whole subnet and single PC, same results. ASDM not enabled on outside interface, only inside.
There is no error messages. I noticed ASDM-LAUNCHER.exe in task manager. Killed it, tried again, but no ASDM screen.
Anything anyone can suggest?
