Problem OSX User Unable to Stay Connected to Ultimate Pack Server

[wastrel]

I recently upgraded my Minecrack Map to Ultimate. The upgrade went smoothly, and most users are able to connect with no issues. Loading new chunks provided the newly generated ores to appear.

The server is running plain Ultimate v1.0.1

One user is unable to connect. Everytime he logs on, he receives just a blank screen. The only message I see on the server end is:

2013-03-10 17:47:13 [INFO] Player lost connection
I had him post the last few lines of his log:

I had him force update his mod pac with no luck. Then delete and resintall FTB in its entirety. I had him update Java 32b and 64b. I have another Mac user on my server that was able to connect using Java, and had the user emulate that version, but still no luck.

I had the player run a traceroute, results:

I hate bumping threads, but I'm hoping the right pair of eyes (or a single eye, far be it for me to discriminate against pirates) sees this and might know a solution.

########## GL ERROR ########## @ Pre render 1281: Invalid value
The game is trying to render textures at a different resolution than it was patched for.
Is he using a texture pack?

 

[wastrel]

I had previously asked if he was using an HD texture pack, he said he was not, but did not clarify if he was using any pack at all. I asked him if he was to try to log on using default

 

[wastrel]

I checked with the user, the pastebin log posted previously is from running default texture pack.

Can there be some setting somewhere that is causing the client to think the TP is HD but it is not.

Please note, the user has already done a fresh install of both the FTB launcher, and the mod pack, and is still receiving the error.
