Screen flickering in Nebulas

[Lieutenant]

Alright, I've been playing Freelancer with the Discovery mod, all settings activated and on highest, the ENBeffect mod is on as well.

The screen flickers rapidly for just a moment in Nebulas. Nothing game-hampering, but still a downer since I never had this problem before. I timed the occurance and it's vageuly familiar to the "lightning clashes" as I call them in certain Nebulas. Like in Corinth's mine field, only instead of a cool flash mixed with the nebula itself, its a nasty screen flicker pasted over the Nebula.

No idea what caused it, game runs at around 250-300 FPS on my rig. I've tried disabling ENB mod and little tweaks with my Nvidia card's settings. Nothing's worked so far.

Rig:

Vista Ultimate 64-Bit
9800 GT Nvidia (1BG DDR3)
Dual Core AMD 64 X2 +3800 (Dual Core)
4 GB RAM

Any takers on this problem, any idea is appreciated.

Something I've considered is I recently installed a new game, but I highly doubt that interfered with anything whatsoever.
