Jim: I know the feeling. Finally decided to summarize what's happened to me since yesterday.
After Wednesday's Windows 7 Update (which dumped me with almost no warning out of STO during a battle with the Fek'ihri in the "Afterlife" KDF mission, and then rebooted my computer; even though I've told Windows Update not to update or reboot without informing me first) and yesterday's STO patch, I can no longer play STO ... at all. At first it usually just crashed to desktop. But after about six or seven failed attempts on my part, it now just freezes my computer without patching more than 0% (and via the pop-up error reporting window, I've reported the game crashing on me at least seven times). All I can do is press the power button until the computer shuts off and then press it again to reboot. I've uninstalled STO, Steam, and ARC. Then I've reinstalled Steam and ARC, and then tried to reinstall STO (including the standalone launcher). Computer froze again. I don't know what else to do. I've had STO freeze on me in the past; I've had STO crash to desktop on me; I've had STO fail to log-in; etc. But those were all temporary; eventually I could log-in and patch okay again. This time, though, I think it's permanent. I can't even tell my newest STO friend that I won't be able to be back on STO again; I don't have her email address. Not exactly the best sign-off after 5 out of 6 years of playing STO. Not a rage-quit. Just a what-else-can-I-do-but-give-up reaction.
Hope you're able to get it fixed on your end.
P.S.: I've checked STO forums (including network bug reports), ARC, Steam, Reddit, Twitter, and other websites. No recent report whatsoever of what happened to me STO-wise. Maybe it's unique to me this time. (Also, I installed World of Warships earlier today. No problems. Logged in. No problems. Played several battles. No problems. Logged out. No problems.) I wish someone could tell me that Cryptic is aware of my STO-related problems and is doing their best to solve it. Or that I just won't be able to play it anymore. Either answer would be okay with me. I would prefer the first answer, however. I miss STO alot already.
Jim: Good news (sort of), bad news.
Bad news first: I still haven't found a solution to the patch freeze/computer freeze problem.
Good news (sort of): There's a third user (Coachles is his or her username) who's reporting the same problem, only they put it into the program bugs forum. I referred them to this forum and this thread. Maybe something of what I've tried (and failed at) will help them. I can only hope so.
Maybe with three of us suffering, Cryptic will take the problem much more seriously (if they haven't already). Knock on wood we three will be back on STO in less than a week. I'd be willing to wait a month, however, if it meant the problem was solved and we three were back on STO again.
