Hey TTG this is probably the wrong section for this but you guys are very helpful, i recently ordered a ISO the first disc they sent me got too 47% when installing and came up with disc unreadable, this happened on all attempts to install (around 5) so they sent me another one but now that one get's to 48% and comes up disc unreadable (3 attempts so far) i though it could have been my laser so i tried installing the retail disc, which installs perfectly.

Does anyone have any advice? the seller is very legit (won't say who due to advertising) and the disc they use are Verbatim, i have also hotswapped multiple time before (GTA 4) so i know what i'm doing.

(both discs have no scratches)
