Atik 383L + variable cooling temperature, error

[sferoida]

Hello
I have 2 Atik cameras: 383L+mono for photos (by Artemis) and Titan for guiding (by PHD2). I have 2 problems with 383L+:
1. variable cooling temperature
The camera is working strangely: the cooling is set to -20 ° C (all the time), status: cooling, the outdoor temperature is + 13 ° C. The temperature of the chip is getting warmer [time, temp.]:
19:51 -20,0
19:58 -17,7
20:00 -16,9
20:02 -15,6
20:04 -14,8
20:06 -14,2
20:10 -12,9
20:13 -12,3
20:19 -11,2
20:23 -10,7
20:29 -10,2
20:35 -9,8
20:37 -9,6
20:40 -9,6
20:47 -9,4 I stop working, turn on Warm up
20:51 +29,3!!! The temperature has changed by 40 degrees in 4 minutes!
20:52 +31,0
20:53 +32,1
20:54 +32,8
20:55 +32,8
20:57 +32,2 starts to fall
20:59 +30,9
21:00 +30,3 it continues to fall

2. upgrade Artemis v. 4.4.0.8 -> 4.1.4.4
I noticed that the cooling temperature is relatively stable (despite the setting at -20 ° C is about -14 ° C) if I do nothing with Artemis. I think: maybe it's a soft fault and you have to upgrade Artemis (that's what I'm doing). After installing the problem was not solved, the cooling is working badly, but the Atik Titan camera that I use for guiding has disappeared   . "Disappeared" means that in the Windows devices it can be seen and not seen by astro programs such as Artemis, Nebulosity, PHD2. So far, I had a list of where Atik Titan and Atik 383+ were. The new version of Artemis does not see 2 cameras at the same time.

I uninstalled Artemis upgrade and (well, I had an old version on my hard drive) I installed an earlier version that I had worked on so far. Titan appeared and Atik 383+ disappeared. On Windows, you can see two cameras: Titan and 383+. Astro programs list where Titan is (and is currently running) and Unrecognized (PID = 0) instead of 383+. When I select the other astro programs are crashing.

I'm working on Windows 10. Power cables and usb checked, the voltage to 383L+ is 13.8V, the programs I downloaded from www.atik-cameras.com. I will say that I had a longer break, the last time I photographed in May 2017 (4 months break). Does it matter?

Can you help?
