Hello. I had electrum 188.8.131.52 installed on my machine. Luckily I backed up my key. Anyway, I came to need an LTC address so I looked for my wallet today (about a month since I installed it) and I see its completely gone from my system. No sign of the program nor the data directory. Only sign of the wallet is the original compressed file for the application. Since installing electrum I also installed bitcoin core but removed it afterwards. I have no idea if it could cause problems or not (though doubt its the culprit). I haven't had a chance to check my cold wallet address to confirm the funds are still there but I'm doing so now to rule out foul play.
edit: cold game that your site has one version, your front page has an earlier version, and this last page here has the latest version.
I'm ONLY installing at this point to get my coins so I can get them off << that's how I feel but I'm not sure I want to do ltc-core, I'll look at the block chain and make a call based on it, I see the coins are still there so its not a wallet stealer or some malware, looks like the software is just uninstalled for some reason.
