Open 1.0.4: Random Crash Bug

[ImHumanGetMeOutOfHere]

Version:
1.0.4

What is the bug:
Computer Stats: (Not Sure How Much is Relevant)
-Windows 7 Home 64 bit
-2x Intel Pentium CPU @ 3.20GHz
-AMD Radeon R7 200 Series Graphics card
-1TB Hard Drive + 60GB SSD
-Generic Scree, Keyboard, Mouse, Headset

I crash at seemingly unrelated times for no apparent reason. It does not happen during a lag spike in particular or anything like opening an interface or crafting something, it just happens. Please help, it's really annoying. It can do it up to every half an hour or so. I get this crash report: (I've cut out the mod list and list of loaded APIs because I presume you know these already and because character limits.)

Chisel: Errors like "[FML]: Unable to lookup ..." are NOT the cause of this crash. You can safely ignore these errors. And update forge while you're at it.
EnderIO: Found the following problem(s) with your installation:
* An unknown AE2 API is installed (rv3 from appliedenergistics2-rv3-beta-5.jar).
Ender IO was build against API version rv2 and may or may not work with a newer version.
* The RF API that is being used (1.7.10R1.0.2 from <unknown>) differes from that that is reported as being loaded (1.7.10R1.1.0 from EnderTech-1.7.10-0.3.2.405.jar).
It is a supported version, but that difference may lead to problems.
This may have caused the error. Try reproducing the crash WITHOUT this/these mod(s) before reporting it.

Can it be repeated:
Haven't seen it in the other bug reports so i guess it's pretty specific to me. No way of purposefully triggering it anyway.

Known Fix:
No Idea

Java.lang.RuntimeException: java.io.FileNotFoundException: E:\Davy\Documents\Curse\Minecraft\Instances\FTB Infinity Evolved Skyblock\saves\1\DIM-1\multipart.dat (The process cannot access the file because it is being used by another process)

Something else is accessing the file. Most likely a virus scanner.

 

[Lone Lycan]

to see whether the virus scanner is the issue... add your FTB directory (find this at the top of the Launcher OPTIONS tab) into your antivirus EXCEPTIONS or EXCLUSIONS list (whatever your antivirus calls it) and see if the problem goes away
