Several users have reported write problems after upgrading, the media been mounted ready-only due to error vs UDF spec not noticed by InCD 3 but seen by InCD 4. Copying the data temporarily to hard disk, reformatting with InCD 4 and copying the data back allows to workaround the issue.
Current 126.96.36.199 has a defect on NT+ systems, crashing during safe mode boot (but not during normal boot). The defect has been fixed in-house, and a version with the fix is in finally qualification phase before publication on the web. You can either update immediately if you are not worried about safemode booting, or wait for the better version which should be available soon.
